QUESTION

Unable to display html file from local storage in webview

Asked 2021-Jun-10 at 11:53

I have a Flutter project in which I am:

Downloading the zip file (full of html files)
Extracting the html files to a new directory (ebooks/02)
Saving the local file urls in a List
Displaying the urls in Webview & iterate through List for back & forth.

However, in the web view all I get is "Unable to load asset..."

Though any standard http url works fine in webview.

I tried from these two answers but no result: Answer1 & Answer2

The exception I get is :

E/flutter (10963): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: Unable to load asset: /data/user/0/com.pts.school_ebook_reader_app_prag/app_flutter/ebooks/04/00.html

I need to understand how to make the local html at the given path display in webview.

Any help would be appreciated.

Edit:

The webview code (currently trying to display only 1st url in list):

 class _BookReaderState extends State<BookReader> {
  List<String> urls = UserData.ebook;

  WebViewController web;
  final _key = UniqueKey();
  String _url;

Code to add files :

Directory dir =
        Directory('${_appDocDir.path}/$folderName/${item.key_name}');
    List<FileSystemEntity> listOfAllFolderAndFiles =
        await dir.list(recursive: false).toList();

    if (UserData.ebook != null) UserData.ebook.clear();

    listOfAllFolderAndFiles.forEach((element) {
      if (element.toString().contains("html")) {
        String url = element.toString().replaceAll("File: ", "");
        url = url.replaceAll("'", "");
        UserData.ebook.add(url.toString());
      }
      UserData.eBookTitle = item.title;
    });

I think you should load html as normal file, not like asset, because it's not located in Assets directory and convert it to base64:

  Future<String> _loadHtmlFromAssets(int n) async {
    final file = File(urls[n]);
    String fileText = await file.readAsString();
    final base64 = base64Encode(utf8.encode(fileText));
    return "data:text/html;base64,$base64";
  }

Then show it like:

return WebView(
    initialUrl: snapshot.data.toString(),
    javascriptMode: JavascriptMode.unrestricted,
  );

QUESTION

Multithreading should close the whole process but doesn't

Asked 2020-Oct-25 at 19:32

I am trying to do a simple executable that import a PDF and with pyttsx3 reads the PDF. As pyttsx3 can't pause the reading I created a small function with psutil that kills the process named Python.exe (May not be the ideal way). a simple interface with Easygui allows to choose the PDF file, the page where to start from, and close the process when a button is pressed (with psutil).

As I understood multi-threading, there should be a main process with multiple thread executing; therefore I thought that closing the whole process I would stop the script whenever the user press the button. It doesn't work. The thread is closed but the main process not, therefore the script keeps running (the voice keep reading). After I have a working version I plan to use pyinstaller to convert it into an exe file.

The code is:

from pyttsx3 import *
from pyttsx3.drivers import sapi5
from PyPDF2 import PdfFileReader
from threading import *
from psutil import process_iter
from easygui import enterbox,fileopenbox,msgbox,choicebox

class Audiobook():

    def readbook(self,title,page=0):
        book = open(title, 'rb')
        pdfReader = PdfFileReader(book)
        pages = pdfReader.numPages
        speaker = init()

        speaker.setProperty('rate',150)
        
        for num in range(page-1,pages):
            page = pdfReader.getPage(num)
            text = page.extractText()
            speaker.say(text)
            speaker.runAndWait()
            speaker.say("You arrived to page" + str(num+1))

    def title(self):
        title = fileopenbox()
        if title:
            page = int(enterbox("From which page would you like to read? ",'Choose the page'))
        else:
            return
        self.readbook(title,page)

    def killprocess(self):
        kill = msgbox("Click here to stop reading","Close the Application?")
        if kill is not None:
            procname = 'Python.exe' #this line will be changed when converted into an executable with pyinstaller
            for proc in process_iter():
                if proc.name() == procname: 
                    proc.kill()

processcontrol = Audiobook()
bookreader = Audiobook()
process1 = Thread(target=bookreader.title)
process2 = Thread(target=processcontrol.killprocess)
process2.start()
process1.start()

Any idea what am I doing wrong? I spoofed Google and this website but without success.

Thanks

ANSWER

Answered 2020-Jun-23 at 08:09

It is obvious. There is a book without any image. Change the img code to this:

@isset ($book->image)
    <img src="{{$book->image->getImage()}}" alt="product image">
@endisset

or use optional method and Null Coalesce Operator to have a default image:

<img src="{{optional($book->image)->getImage() ?? 'default_image_path.png'}}" alt="product image">

or this one:

@if (isset($book->image))
    <img src="{{$book->image->getImage()}}" alt="product image">
@else
    <img src="default_image_path.png" alt="product image">
@endif

I hope this helps you.

QUESTION

MongoDB - embedding, inserting one collection into another

Asked 2020-Jan-06 at 12:44

If I have a collection (named e.g. people) that looks like

{
   _id: ObjectID("5e12f6260c190f8ee91b162d"),
   name: "Joe Bookreader",
   address: "Highway To Hell 21"
 }

and I want to remove this value for address, and embed the collection (addresses) into it:

               {
                  _id: ObjectID("5e25fg3gjh48ee91b2653"),
                  street: "123 Fake Street",
                  city: "Faketon",
                  state: "MA",
                  zip: "12345"
                }

to look like:

{
   _id: ObjectID("5e12f6260c190f8ee91b162d"),
   name: "Joe Bookreader",
   address: [
                {
                  street: "123 Fake Street",
                  city: "Faketon",
                  state: "MA",
                  zip: "12345"
                }
              ]
 }

How would I do this?

Would it be something similar to inserting the new column, like in the code below (or something completely different)?

 var bulkInsert = db.people.initializeUnorderedBulkOp()
 db.addresses.find().forEach(
    function(doc){
      bulkInsert.insert(doc);
    }
  )

Any help would be appreciated, thanks!

ANSWER

Answered 2020-Jan-06 at 12:44

You can run $lookup with empty pipeline to embed one (entire collection) into another.

db.people.aggregate([
    {
        $lookup: {
            from: "addresses",
            pipeline: [ ],
            as: "addresses"
        }
    }
])

Mongo Playground

Then you can either use $out (replace the output collection entirely with aggregation result) or $merge (incorporates aggregation results into existing collection):

EDIT:

You can add $match to target single document instead of entire collection:

db.people.aggregate([
    {
        $lookup: {
            from: "addresses",
            pipeline: [ { $match: { street: "123 Fake Street" } } ],
            as: "addresses"
        }
    }
])

Dagger2 not finding provided instance

Asked 2020-Jan-03 at 08:20

I'm facing some issues trying to use Dagger with multiple Components, I have the following (each class is in its own file):

Scopes:

@Scope
@Retention(AnnotationRetention.RUNTIME)
annotation class PrototypeScope

Modules:

@Module(includes = [RepositoriesModule::class])
class GetRandomBookUseCaseModule {

    @Provides
    @Singleton
    fun provideGetRandomBookUseCase(booksRepository: BooksRepository) =
        GetRandomBookUseCase(booksRepository)
}


@Module
class RepositoriesModule {

    @Provides
    @Singleton
    fun providesBooksRepository(): BooksRepository = BooksRepositoryImpl()

    @Provides
    @Singleton
    fun providesPreferencesRepository(): PreferencesRepository = PreferencesRepositoryImpl()
}


@Module
class BookReaderModule(val ctx: Context) {

    @Provides
    @PrototypeScope
    fun provideBookReader(getRandomBookUseCase: GetRandomBookUseCase) =
        BookReader(ctx, getRandomBookUseCase)
}

Components:

@Component(
    modules = [GetRandomBookUseCaseModule::class]
)
interface UseCasesComponent {

}

@Component(
    dependencies = [UseCasesComponent::class],
    modules = [BookReaderModule::class]
)
@PrototypeScope
interface BookReaderFragmentComponent {

    fun inject(bookReaderFragment: BookReaderFragment)
}

Then, in BookReaderFragment I have the following:

class BookReaderFragment : Fragment() {
    @Inject lateinit var bookReader: BookReader
    val component: BookReaderFragmentComponent by lazy {
        DaggerBookReaderFragmentComponent
            .builder()
            .useCasesComponent(DaggerUseCasesComponent.create())
            .bookReaderModule(BookReaderModule(context!!))
            .build()
    }

    override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)
        component.inject(this)
        ...
    }

    ...
}

However, Dagger is failing ought to:

error: GetRandomBookUseCase cannot be provided without an @Inject constructor or an @Provides-annotated method.

What is going on? Why Dagger is not finding the provided method?

Thanks a lot

UPDATE: Adding RepositoriesModule as included in GetRandomBookUseCaseModule. After this change, I have realised that, although the error message, the issue is related with the way the BookReader is injected. If I remove the @Injected from the BookReaderFragment this way:

class BookReaderFragment : Fragment() {
    lateinit var bookReader: BookReader
    val component: BookReaderFragmentComponent by lazy {
        DaggerBookReaderFragmentComponent
            .builder()
            .useCasesComponent(DaggerUseCasesComponent.create())
            .bookReaderModule(BookReaderModule(context!!))
            .build()
    }

    override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)
        component.inject(this)
        ...
    }

    ...
}

Then there's no error, however it will not work on runtime, but when the @Inject is set, then the error is thrown.
