A simple Django app to automatically translate the pot (.po) files generated by django's makemessages command using google translate.

django-autotranslate's Issues

Alternative Translation Service Backends

Alternative to Google Translate API

Efficient API Usage

Hello,

Currently, the library translates for each word within the po files. I think that it should check whether related message id is translated before or not. This helps us to improve the efficiency of using the Google Translate API.

List index out of range

when we type in terminal
python manage.py translate_messages -l de

UTF-8 encodings break the entire .po file

To Fix change add codecs usage to the code in translate_messages.py as the following:

from autotranslate.utils import translate_strings

from django.conf import settings
from django.core.management.base import BaseCommand

from optparse import make_option

import os
import codecs

class Command(BaseCommand):
    help = ('autotranslate all the message files that have been generated '
            'using the `makemessages` command.')

    option_list = BaseCommand.option_list + (
        make_option('--locale', '-l', default=[], dest='locale', action='append',
                    help='autotranslate the message files for the given locale(s) (e.g. pt_BR). '
                         'can be used multiple times.'),
    )

    def add_arguments(self, parser):
        # Previously, only the standard optparse library was supported and
        # you would have to extend the command option_list variable with optparse.make_option().
        # See: https://docs.djangoproject.com/en/1.8/howto/custom-management-commands/#accepting-optional-arguments
        # In django 1.8, these custom options can be added in the add_arguments()
        parser.add_argument('--locale', '-l', default=[], dest='locale', action='append',
                            help='autotranslate the message files for the given locale(s) (e.g. pt_BR). '

@ankitpopli1891 If you're open to adding this functionality, I'd love to take a crack at it over the weekend.

goslate dependency has been abandoned/deleted

One of the dependencies, goslate, has been abandoned and deleted by its author. It needs to be replaced.

Google has updated its translation service recently with a ticket mechanism to prevent simple crawler program like goslate from accessing. Though a more sophisticated crawler may still work technically, however it would have crossed the fine line between using the service and breaking the service. goslate will not be updated to break google’s ticket mechanism. Free lunch is over. Thanks for using.

Source: https://pypi.org/project/goslate/

Google Translate requirement should be optional

The library is dependent on Google API Python Client which may or may not be used.

Lets keep it optional. It should be installed separately if it is required.

Finding the first .mo file breaks the loop

Change the keyword to continue instead of return here or it will not continue parsing other languages than the first one.

Do i need google API Key to get this app working?

I am planning to use this app, so do i need Google Translate API Key to make it work??

The function `translate_strings` returns wrong value then it called twice

from autotranslate.services import translate_strings

res1 = translate_strings(['Hello'], 'de', 'en', False)
res2 = translate_strings(['Hello'], 'fr', 'en', False)

django-autotranslate/autotranslate/services.py

Line 77 in de4c2c9

def translate_strings(self, strings, target_language, source_language='en', optimized=True):

The result of the first call contains one translation into 'de' language as expected.
But the result of the second call contains two translations and the first result element is the translation into 'de' language from the first function call. It seems the function accomulates results between calls.
I expect the result for the second function call has only one translation into 'fr' language.

Alternative source language

I believe that is a good feature the possibility of translate from other language diferente of us.
You may create create in settings.py like source_language=xx and default is us.
tks.

Too many text segments Error

Google Translate API V2 has a limitation per each request should have 128 query entries. I think current version sends without limitation.

Getting 503 Service Unavailable Error

I am getting

`

According to https://stackoverflow.com/questions/59809785/i-get-a-attributeerror-module-collections-has-no-attribute-iterable-when-i

this is because collections.Iterable is deprecated. Replace it with collections.abc.Iterable.

As a test I modified the code

Is there an updated version of this or any alternatives available, or am I missing an import somewhere?

Multiline msgids are not processed correctly

Something like

msgid ""
"Multiline\n"
"Text"

is not supported ATM although very common.

Can translate only from English

In autotranslate/management/commands/translate_messages.py : 96 hardcoded 'en' as source_language.

Better set to settings.LANGUAGE_CODE or add own setting var for this app

Django autotranslate installation fails

I keep getting this error anytime I attempt to install the package. I'm trying to install it within a docker environment.

pip3 install --upgrade -r test.txt

It gives the error below

IndexError while running the app using GOOGLE_TRANSLATE_KEY

I am getting the following error while running translate_messages. I have generated a Google Translate API key and set it as GOOGLE_TRANSLATE_KEY as well.

%(placeholder)s incorrect when translating to Chinese Characters

When converting something like
Hello %(placeholder)s

To Chinese becomes:
您好％（占位符）

The % symbol becomes a different Unicode character ％.
The ( character also becomes a different Unicode character （ .
Also sometimes the s disappears or moves.

And so this unfortunately fails at the compilemessages stage
