How can I add new courses to EdX via api ? openedx has some built-in REST api for this or should we create custom api to add courses?
As we know EdX has the EdX studio which provides the UI to add new courses. say if we have like 3k courses, it is a tedious task to add each one of them manually through EdX studio. If we don't have any API in place can we create these api's on our own. I understand that edx-platform has the django-rest-framework out of the box. It should be possible to create custom API's but I am not sure how complex the model of EdX is as we have a number of functionalities and customizations associated with a course in EdX. -
How to rendering python variable in html template?
i need to change old value to new value in template file. Actually, when user enter 10 digits mobile number python function will call. if i check in log it's showing value but in html file it's showing value. how to get that value in second time? views.py from django.views.decorators.csrf import csrf_exempt import json @csrf_exempt def default(request): if request.is_ajax(): print("inside the ajax") phone_no = request.POST.get('phone_no') print(phone_no) dict = {'phone_no': phone_no} template_name = 'mobile_recharge.html' extended_template = 'base.html' dummy_var = 'test' print(dummy_var) if request.user.is_authenticated(): extended_template = 'base_login.html' return render(request,template_name, {'extended_template': extended_template,'phone_no': phone_no,'dummy_var': dummy_var}) template_name = 'mobile_recharge.html' extended_template = 'base.html' dummy_var = 'test' if request.user.is_authenticated(): extended_template = 'base_login.html' return render( request, template_name, {'extended_template': extended_template,'dummy_var': dummy_var} ) script <script type="text/javascript"> $(document).ready(function () { $('#phone_number').on('input', function () { if ($(this).val().length >= 10) { alert("user enter 10 digits numbers"); var phone_no = $('#phone_number').val() console.log(phone_no); $.ajax({ type: "POST", url: "http://localhost:8090/", data: {'phone_no' : phone_no}, dataType: "json", success: function(msg) { //alert(msg.phone_no); } }); return; } }); }); </script> html {{phone_no}} {{ dict }} {{dummy_var}} If i call above variables in templates. i didn't get any result.

IntegrityError at /accounts/regist_save/
I got an error, IntegrityError at /accounts/regist_save/ UNIQUE constraint failed: authtoken_token.user_id . The Traceback shows /Users/Desktop/accounts/views.py in regist_save user = form.save() ▶ Local vars I cannot understand why this part is wrong. I wrote in views.py @require_POST def regist_save(request): form = RegisterForm(request.POST) if form.is_valid(): form.save() return redirect('registration/accounts/index.html', context) context = { 'form': form, } return render(request, 'registration/accounts/regist.html', context) User regist form firstly had username&password validation system.They could work well.I added email validation system this time,but so I got this error.What can I do to fix it? -
Trying to use formset, getting __init__() got an unexpected keyword argument 'instance'
I need to use formset, and successfully implemented it for adding objects. But now i need to use formset for editing objects. I have following: models.py class Cell(models.Model): content = models.CharField(max_length=100) row = models.ForeignKey('Row') class Row(models.Model): pass forms.py class RowForm(forms.Form): cell = forms.CharField(label="Ячейка", max_length=100) number_of_cells = 5 RowFormset = formset_factory(RowForm, extra=number_of_cells) views.py def edit_row(request, row_pk): try: row = Row.objects.get(pk=row_pk) except Row.DoesNotExist: return HttpResponse('Такая строка не существует') if request.method == 'POST': formset = RowFormset(request.POST, instance=row) if formset.is_valid(): formset.save() return HttpResponseRedirect(reverse('table:index')) else: formset = RowFormset(instance=row) return render(request, 'table/edit-row.html', {'formset': formset}) Currently i'm getting TypeError: __init__() got an unexpected keyword argument 'instance'. How can i accomplish my task getting into account that using model form is likely not an option because model doesn't know anything about my cells, or the number of cells i should have in a row (so i presumably must stick to ordinary forms.Form). Thank you. -
Django (1.10.4) Migrations not applying datetime field changes(copies) in runpython
Changes in runpython are never applied for datetimefield. I'm adding a new datetimefield on a model with an optional default of timezone.now() model date = models.DateTimeField(default=timezone.now) migrations operations = [ migrations.RunPython(add_expense_date), migrations.AddField( model_name='expense', name='date', field=models.DateTimeField(default=django.utils.timezone.now), preserve_default=False, ),] I wrote a migrations.RunPython method that copies the values of another field _created_at to the new field date for existing fields. def add_expense_date(apps, schema_editor): Expense = apps.get_model("accounting", "Expense") db_alias = schema_editor.connection.alias for expense in Expense.objects.using(db_alias).all(): expense.date = expense._created_at expense.save() Problem is, it always applies the defaut value and never applies the changes in the runpython calls. The runpython methods do get called however. When I make the field nullable, it defaults all the values to null instead of the changes in the runpython call -

How to reuse django-model in elasticsearch and neo4j?
I am developing a django application in python. It consists several models. It makes uses of MySQL relation database. For certain features, it also makes use of elasticsearch and neo4J graph database. I am using elasticsearch_dsl library for elasticsearch and neomodel library for dealing with neo4j. For certain models, when new object is created, it's entered into elasticsearch and neo4j, along with MySQL. I am required to redefine same model(which i defined for django-orm)for elasticsearch_dsl and neomodel also. As a result, in my project, there're three different types of definition of same model. Is there any DRY way to do this ? I mean, I want to define model for django-orm and then elasticsearch_dsl and neomodel library automatically creates their model representation from django-model representation. Apologizing for poor english. Thanks in advance. -
UserCreationForm show error when fields are empty
I'm using Django built in UserCreationForm. I want to show message under the field when that field is empty and user tring to submit form. Unfortunatly I see only built-in behavior of browsers like "fill out this field", by the way in different browsers that behavior is different. Some browsers just encircle the field box with a red line. How to turn off this behavior and show message under the field. Why .error_messages didnt work?!

A page is not loaded
A page is not loaded. I got no error, but surely link is not good.

Django and HTML5 application cache: index page is loaded from cache and csrf token is not available
I am using the latest django for my app, and recently I added application cache for the app to be available offline. I listed the necessary static resources in the CACHE list, for all other resourses I defined NETWORK *, so everything actually works as I expect. But there is such a problem - login fails due to incorrect csrf token in Google Chrome. It turns out that, even when online, Chrome loads the index page from cache and the fresh csrf cookies are not received, although I did not specify the index page in the list of cached resources. Is there any way to force load the index page when online? Or maybe you know some other work-around? In FF it works well, it loads the page from the server when online. I found one possible solution HTML5 cache and authorization issues but by default, django csrf token is changed per each request. -
Django Haystack Query
I am having a difficult time to figure out how to do a query with Djanog Haystack. I am using Elasticsearch as backend. I have a field which can be any string. And I want to query to get all entries that has any value in a list or empty. Here is an example: Let's say the field is called key and the strings in a list val_list = ['abc', 'def', ''] I tried SearchQuerySet().filter(key__in=val_list) But it does not work. I think the issue is with the empty string ''. I found some posts that use Raw("[* TO *]") to filter if a string is not empty and then use exclude to find empty ones. It works perfectly if it is used by itself. But how can I combine it with other possible values in the list? -

Is it possible to use Python SpeechRecognition on Django?

pass argument to view with reverse django
I have a view create_rating where after I submit a form I want it to be processed on a view rating_upload and then i want to redirect back to the create_rating view. Cant seem to get it to work, my latest code below. I would think when i click submit on the create-rating page that it should send video_id to rating_upload, and from there I can just send it back to create_rating as an argument.

Properly labeling multiple form fields with Django
I have a simple login screen with a Username and Password input, I want to label each field so that if a user were to click on 'Username' or 'Password' it would automatically toggle the control to the field. Like the Facebook homepage does for example. My problem is that I don't know how I should properly use the <input tags: <form action="/login/" method='post'> <label for='username_info'> Username </label> {% csrf_token %} {{ form.username }} <p> <label for="password_info"> Password </label> {{ form.password }} <p> <input id='username_info' type='submit'> </form> So that works for the Username text but not for the Password text obviously. How do I properly label each field? I looked at the Django Docs example but when I try to use a django template tag as the value attribute for the input tag it only displays the raw html in the field. -
