database insert from a model, no such column exception,

database insert from a model, no such column exception, - java

firstly i have trouble with creating database,then i want to put my received huge json datas(i converted json to java model by GsonBuilder and i saw all the datas in my entity[] list which made from ReceivedEntityModel class) to database,but i failed at first steps.it never creates my columns,so that after insertion there is 0 rowcount:(, i read all those answers about this topic and they didn't help me at all.I'm stuck.Anyone can help??

this is Setup.java,fetchEntities(),AddNewEntity() functions are calling from there.Gson Builder make me a model.And the i call AddNewEntity()
protected String doInBackground(String... urls) {
entityReqestInfo = new EntityReqestInfo();
String cevap = POST_FOR_ENTITY(urls[0], entityReqestInfo);
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
receivedEM = gson.fromJson(cevap, ReceivedEntityModel[].class);
myDB.getDatabaseEntityOperations().AddNewEntity(receivedEM);
pDialog.cancel();
return cevap;

Where are the column names defined?
The DefaultDimension2 column is not created with the intended name
in your table, because you forgot a space here:
+ DefaultDimension2 + "INTEGER, "
It must be
+ DefaultDimension2 + " INTEGER, "
So, supposing that the DefaultDimension2 column name is defined as
public String DefaultDimension2 = "DefaultDimension2";
it is actually created as "DefaultDimension2INTEGER, " instead of "DefaultDimension2 INTEGER, "
It's really a common mistake, mostly due to hurry.

Java Bean Return Value is Null

I'm getting a problem with the return value after the post request, the response string contains the requested JSON text but the dataBean is null ??
#Override
public wDataBean doInBackground(Void... params) {
wDataBean dataBean = new wDataBean();
try {
Response response = client.newCall(request).execute();
String responseString = response.body().string();
JSONObject jsonObject = new JSONObject(responseString);
Gson gson = new Gson();
dataBean = gson.fromJson(jsonObject.toString(), wDataBean.class);
}
catch (final IOException e)
{
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_SHORT).show();
}
});
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(MainActivity.this,e.getMessage(),Toast.LENGTH_SHORT).show();
}
return dataBean;
}
This is a sample of the response:
{ "IsOK":true,
"Response":"Logged in successfully",
"MyArray":{ "user":"35",
"email":"email#domain.com",
"img":"https:\/\/www.mywebsite.com\/uploads\/136_image.png",

"lname":"Last Name",
"myToken":
{
"auth":"xyzxyzyxyzxyzxyzxyzxyzxyzxyzxyzxyzxyz",
"expiry":"1980-01-01 00:00:00"
}
},
"myToken":{}
}
wDataBean.java
public class wDataBean {

public Main1 getMain() {return main;}
public void setMain(Main1 main) {this.main = main;}

Can you show me the class wDataBean?
But I venture to say that this can solve

A bit on Mongo Query Language
In MongoDB, the $slice operator controls the number of items of an array that a query returns. The $slice operator can accept values with following syntax:
[toSkip, toLimit]
Where the first value indicates the number of items in the array to skip and the second value indicates the number of items to return. For example, you can use the following query:
db.discussions.find({}, {messages: {$slice: [20, 10]}})
To return 10 messages, after skipping the first 20 messages of that array.
Bring it to Spring Data World
In order to use $slice operator with Spring Data MongoDB, you should use #Query annotation and its fields attribute. For example, if you have a DiscussionRepository, you could write something like:
public interface DiscussionRepository extends MongoRepository<Discussion, String> {
#Query(value = "{}", fields = "{messages: {$slice: [?0, ?1]}}")
List<Discussion> findDiscussions(int skip, int limit);
}
With this arrangement, following method call:
discussionRepository.findDiscussions(20, 10)
Would generate the same result as:
db.discussions.find({}, {messages: {$slice: [20, 10]}})
With a little bit of work, you can turn the Skip/Limit combination to a pagination functionality.

Converting a json array to json object in android using gson?

I am passing a json array from activity A to activity B.Then I am using the GSON library to insert a value into the array.This is my current code.
public void gsonResponse(String json) {
try {
JSONObject jsonObject = new JSONObject(json);
JSONArray jsonArray = jsonObject.getJSONArray("result");
for (int i = 0; i < jsonArray.length(); i++) {
LinkedHashMap<String, String> linkedHashMap = new LinkedHashMap<>();
JSONObject innerJosonObject = new JSONObject(jsonArray.getString(i));
// you need to put all values from jsonObject to map for managing the order..
linkedHashMap.put("doc_no", textViewInvNo.getText().toString());
linkedHashMap.put("itembarcode", innerJosonObject.getString("itembarcode"));
linkedHashMap.put("net_wt", innerJosonObject.getString("net_wt"));
linkedHashMap.put("gross_wt", innerJosonObject.getString("gross_wt"));
linkedHashMap.put("stone_wt", innerJosonObject.getString("stone_wt"));
linkedHashMap.put("stone_amt", innerJosonObject.getString("stone_amt"));
linkedHashMap.put("rate", innerJosonObject.getString("rate"));
linkedHashMap.put("making", innerJosonObject.getString("making"));
linkedHashMap.put("qty", innerJosonObject.getString("qty"));
linkedHashMap.put("net_rate", innerJosonObject.getString("net_rate"));
linkedHashMap.put("item_total", innerJosonObject.getString("item_total"));
linkedHashMap.put("sum_total", innerJosonObject.getString("sum_total"));
Gson gson = new Gson();
// convert linkedHashMap to json string and it will keep the insertion order..
String string = gson.toJson(linkedHashMap, LinkedHashMap.class);
jsonArray.put(i, string);
}
jsonObject.put("result", jsonArray);
String jsonResp = jsonObject.toString();
jsonFormattedString = jsonResp.replaceAll("\\\\","");
Log.d("NEW JSON", jsonFormattedString);
} catch (JSONException e) {
e.printStackTrace();
}
}
The output for this is :-
{"result":["{"doc_no":"ES101","itembarcode":"BRMS","net_wt":"10","gross_wt":"1","stone_wt":"0","stone_amt":"0","rate":"32000","making":"100","qty":"1","net_rate":"32100.0","item_total":"32100.0","sum_total":"64600.0"}",
"{"doc_no":"ES101","itembarcode":"MSAA0015","net_wt":"10","gross_wt":"11","stone_wt":"100000","stone_amt":"1","rate":"32000","making":"500","qty":"1","net_rate":"32500.0","item_total":"32500.0","sum_total":"64600.0"}"]}
But my desired output should be something like :-
[{"doc_no":"IN1001","itembarcode":"BRMS123456\nFLT22K","net_wt":"10","gross_wt":"10","stone_amt":"0","rate":"29000","making":"999","qty":"1","net_rate":"29999.0","item_total":"29999.0","sum_total":"30299.0","stone_wt":"0"},
{"doc_no":"IN1001","itembarcode":"BRMS\nGA24K","net_wt":"10","gross_wt":"1","stone_amt":"0","rate":"32000","making":"100","qty":"1","net_rate":"","item_total":"","sum_total":"30299.0","stone_wt":""}]
How can I achieve it? Any suggestion or help is appreciated.Thank You.

Actually you don't need the following line:
jsonObject.put("result", jsonArray);
Just use the existing jsonArray like the following:
String jsonResp = jsonArray.toString();
One other note. you will get extra " " in your response and that is because of jsonArray.put(i, string); statement in the for loop which inserts extra " ". you can simply use the following to fix that:
jsonResp = jsonResp.replaceAll("\"[{]", "{");
jsonResp = jsonResp.replaceAll("[}]\"", "}");

And Parse the json by GSON ->
Gson gson = new Gson();
DocInfoModel[] docModel = gson.fromJson(RESPONSE_STRING,DocInfoModel[].class);

I would suggest to create Model class for your GSON implementation.
Check out this solution.
private void testDoc()

String json = "{\"result\":[{\"doc_no\":\"ES101\",\"itembarcode\":\"BRMS\",\"net_wt\":\"10\",\"gross_wt\":\"1\",\"stone_wt\":\"0\",\"stone_amt\":\"0\",\"rate\":\"32000\",\"making\":\"100\",\"qty\":\"1\",\"net_rate\":\"32100.0\",\"item_total\":\"32100.0\",\"sum_total\":\"64600.0\"},{\"doc_no\":\"ES101\",\"itembarcode\":\"MSAA0015\",\"net_wt\":\"10\",\"gross_wt\":\"11\",\"stone_wt\":\"100000\",\"stone_amt\":\"1\",\"rate\":\"32000\",\"making\":\"500\",\"qty\":\"1\",\"net_rate\":\"32500.0\",\"item_total\":\"32500.0\",\"sum_total\":\"64600.0\"}]}";

Retrofit 2 (in Android) after implementation, Where are my JSON elements?

I'm implementing a retrofit 2 interface to parse JSON elements (video urls, thumbnails, title etc.)
JSONschema2Pojo resulted in 4 pojo classes, but the main/root one is VideoInfo (never mind implements Parcelable, I'm not yet doing anything with it)
Is the lack of #SerializedName("....") affects anything, knowing that this was automatically generated by jsonschema2pojo ? UPDATE : generated new pojo classes, this time with Gson annotations (#SerializedName("") and #Expose) but still having the same problem.
import android.os.Parcel;
import android.os.Parcelable;
import java.util.ArrayList;
import java.util.List;
public class VideoInfo implements Parcelable {
private List<Item> items = new ArrayList<Item>();
private int pageNumber;
private int pageSize;
private int totalCount;
/**
* No args constructor for use in serialization
*
*/
public VideoInfo() {
}
/**
*
* #param totalCount
* #param items
* #param pageSize
* #param pageNumber
*/
public VideoInfo(List<Item> items, int pageNumber, int pageSize, int totalCount) {
this.items = items;
this.pageNumber = pageNumber;
this.pageSize = pageSize;
this.totalCount = totalCount;
}
/**
*
* #return
* The items
*/
public List<Item> getItems() {
return items;
}
/**
*
* #param items
* The items
*/
public void setItems(List<Item> items) {
this.items = items;
}
/**
*
* #return
* The pageNumber
*/
public int getPageNumber() {
return pageNumber;
}
/**
*
* #param pageNumber
* The page_number
*/
public void setPageNumber(int pageNumber) {
this.pageNumber = pageNumber;
}
/**
*
* #return
* The pageSize
*/
public int getPageSize() {
return pageSize;
}
/**
*
* #param pageSize
* The page_size
*/
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
/**
*
* #return
* The totalCount
*/
public int getTotalCount() {
return totalCount;
}
/**
*
* #param totalCount
* The total_count
*/
public void setTotalCount(int totalCount) {
this.totalCount = totalCount;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
}
}
UPDATE: in the class VideoInfo above you can see private List<Item> items = new ArrayList<Item>(); this is because there's another pojo class that has a list of tiems, as follows:

I have created a retrofit interface VideoInterface.class

import retrofit2.http.GET;
/**
* retrofit 2 interface
*/
public interface VideoInterface {
String apiURL = ".....";
#GET(apiURL)
public Call<VideosResponse> listVideos();
}
I have created a response/parse class VideosResponse.java
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import java.util.ArrayList;
import java.util.List;
/**
*/
public class VideosResponse {
//initalizing the collection
List<VideoInfo> videos;
public VideosResponse() {
videos = new ArrayList<VideoInfo>();
}
//parsing the response
public static VideosResponse parseJSON(String response) {
Gson gson = new GsonBuilder().create();
VideosResponse videosResponse = gson.fromJson(response, VideosResponse.class);
return videosResponse;
}
}
UPDATED :Finally I'm calling the API , but not able to get the individual elements
I know I should be able to do something like response.body().getItem().getID().getRendition().getUrl() for example, but I don't see it in the auto complete and if I write it I get errors.
This code is in my onResume() method , the reason why I've commented out public static below is because it's not allowed within the onResume()
// Creating a simple REST adapter which points the API
// public static
final String BASE_URL = "http://api......";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
// Creating an instance of our API interface.
VideoInterface service = retrofit.create(VideoInterface.class);
Call<VideosResponse> call = service.listVideos();
call.enqueue(new Callback<VideosResponse>() {
#Override
public void onResponse(Call<VideosResponse> call, Response<VideosResponse> response) {
VideosResponse videoResponse = response.body();
}
#Override
public void onFailure(Call<VideosResponse> call, Throwable t) {
}});
Everything to the last step seems be alright (no errors), the following logs gives me:
Log.d("Videos ", response.message()); //OK
Log.d("Videos ", String.valueOf(response.isSuccess())); //TRUE
Log.d("Videos ", String.valueOf(response.code())); //200
but I'm still not able to get the strings I need. When I print the log for the response show the response VideosResponse videoResponse = response.body(); I get : VideosResponse#3b8bfaa4 , is this normal? how can I use this?
Is using parcelable advised? will it change anything?

You need to show us the json response or you can figure out on your own also. Basically the object attributes name must match the json attributes, you can debug to see whether the elements are receiving the value or not, in case they are not then add the SerializedName annotation to it. From there onwards there are two possibilities either you have an object or an array. For which you can further create a POJO or create a attribute of type List.

I know I should be able to do something like response.body().item.getID() for example
Um, no, not based on the code as I understand it.
response here would appear to be Response<VideosResponse> response
response.body() therefore would be a VideosResponse
response.body().item will fail, as VideosResponse does not have an item field
When I print the log for the response show the response VideosResponse videoResponse = response.body(); I get : VideosResponse#3b8bfaa4 , is this normal?
Yes. That is the default toString() output for a Java object that has not overridden toString(). This shows that response.body() is a VideosResponse.
I have created a response/parse class VideosResponse.java
Then you know that VideosResponse does not have anything named item. Gson does not add methods to your classes; it only populates instances of those classes, based on parsing some JSON.
If you are expecting VideosResponse to have an item field, make sure that exists in your JSON, and then edit VideosResponse to have an item field.

add a toString() to your VideoInfo class and then onResponse you can log the single object of the returned list with something like
for (VideoInfo videoInfo : videoResponses)
Log.d(LOG_TAG, "VideoInfo: " + videoInfo.toString());

Expected BEGIN_OBJECT but was STRING with custom TypeAdapter

So I'm trying to solve a problem that I have with my custom TypeAdapter with Gson and Retrofit. I keep getting a Expected BEGIN_OBJECT but was STRING error but I'm not really sure how to solve it. Previously I was getting a Expected BEGIN_ARRAY but was STRING error and I solved that. I'm not sure if it needs to be the same way with this new error. I've listed my classes below and any help is appreciated. This is what my json looks like here: http://pastie.org/private/bfo86iznldacbz10rtsdsg The main problem is the multimedia field in the json. It's an empty string if there is no value but if there is a value, it returns a jsonarray that contains jsonobjects.

I know it's a lot of code to go through but I'm looking for any help to solve this problem so I'm trying to be as clear as I can.

I was able to get a solution by implementing a custom JsonDeserializer and then adding that to the RestAdapter like so:
public class ResultsDeserializerJson implements JsonDeserializer<Result> {
#Override
public Result deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
JsonElement titleElement = json.getAsJsonObject().get("title");
JsonElement multimediaElement = json.getAsJsonObject().get("multimedia");
if (multimediaElement.isJsonArray()) {
return new Result(
titleElement.toString(),
(Multimedia[]) context.deserialize(multimediaElement.getAsJsonArray(), Multimedia[].class));
} else if (multimediaElement.getAsString().equals("")) {
Multimedia multimedia = new Multimedia();
multimedia.setFormat("");
multimedia.setUrl("");
return new Result(titleElement.toString(), multimedia);
} else {
Log.d("ResultsDeserializerJson", multimediaElement.toString());
throw new JsonParseException("Unsupported type of multimedia element");
}
}
}
Inside Result.java I added the following constructor (note you can add more parameters for things like section, subsection, etc.):
public Result(String title, Multimedia ... multimedia) {
this.mTitle = title.replace("\"", "");;
mMultimedia = Arrays.asList(multimedia);
}
Then for my RestAdapter I do the following:
private NYTimesService() {
Gson gson = new GsonBuilder()
.registerTypeAdapter(Result.class, new ResultsDeserializerJson()).create();
mAsyncRestAdapter = new RestAdapter.Builder()
.setEndpoint(API_URL)
.setConverter(new GsonConverter(gson))
.setRequestInterceptor(new RequestInterceptor() {
#Override
public void intercept(RequestFacade request) {
request.addEncodedQueryParam("api-key", API_KEY);
}
})
.setLogLevel(RestAdapter.LogLevel.FULL)
.build();
}
I created a custom application to get this working and the repository is open sourced here:

This is still somewhat of a hackish solution, and I feel like it is not the most optimal, but I was able to get the following in the time I figured out the solution:
