Django overriding detail view get method
This is my post detail view and it works perfectly. class PostDetailView(DetailView): model = Post context_object_name = 'post' template_name = 'posts/detail.html' def get_queryset(self, *args, **kwargs): request = self.request pk = self.kwargs.get('pk') queryset = Post.objects.filter(pk=pk) return queryset def get_context_data(self, **kwargs): context = super(PostDetailView, self).get_context_data(**kwargs) content['comments'] = Comment.objects.all() return context However, when I add get method to the view it does not work anymore. def get(self, request, *args, **kwargs): # how to return here so that it works exactly like before After adding get method get_queryset and get_context_data do not gets called automatically and the context is empty in the template. So what would be the get method so that it works exactly like before? -
How can I load the last page only once?
It seems easy but somehow I couldn't wrap my head around it. So basically I have a Django pagination for the posts. Through API I get the number of the pages, and I want to load the last page once, but with this solution, the last page gets loaded into the dataSource once more. Function makeRemoteRequest = () =>{ const {page} = this.state setTimeout(()=>{ axios.get(URL+'/api/posts/?page='+page, {headers: {'Authorization':'Token '+this.props.screenProps.jwt}}) .then((response) => { this.setState({ dataSource: page===1 ? response.data.post : [...this.state.dataSource,...response.data.post], loading: false, refreshing:false, user: response.data.current_user, last_page: response.data.last_page, doRefresh:false }); handleLoadMore = () =>{ if(this.state.page >= this.state.last_page){ this.setState({ page: this.state.page + 1 },()=>{ this.makeRemoteRequest() }) } } -

How to extend Django's test database with custom SQL view?
I'm using Django 2.1 with MySQL. I have one custom SQL view, which is bound with a model with Meta managed = False. Django's TestCase has no idea how the view is created, so I'd like to provide SQL command to create this view. The best option would be to do this on database create, but I have no idea how to do that. What I've done so far was to override TestCase's setUp method. It looks like that: class TaskDoneViewTest(TestCase): def setUp(self): """ Create custom SQL view """ cursor = connection.cursor() file_handle = open('app/tests/create_sql_view.sql', 'r+') sql_file = File(file_handle) sql = sql_file.read() cursor.execute(sql) cursor.close() def test_repeatable_task_done(self): # ... def test_one_time_task_done(self): # ... I've got this solution from similar SO post: How to use database view in test cases. It would be a nice temporary solution, but the problem is with all those 2 test cases active I'm getting following error: $ python manage.py test app.tests Creating test database for alias 'default'...

Two forms one view - Value is not coming from Form - Django
I have two forms and their models are related to each other and i am trying that both of them should get saved in database simultaneously. My one form (sim_form) will be updated while my other form (payment_form) will be saved using the same button.

Django user foreignkey not saving the user
In my model i added the following line: user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True, editable=False), so that when the form saves some data to that table, it will also save the user who saved that data. This is the entire model: class MyModel(models.Model): key = models.CharField(max_length=200) secret = models.CharField(max_length=200) user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True, editable=False) def save(self): # ALL the signature super(MyModel, self).save() When the user saves a key and a secret code, there should also be saved the user id of the user whose key it is. The problem with the actual code, is that instead of saving the id, i'm seeing a NULL below the user id column. I'm using the same system on another model and it works fine, can someone help me find the issue? This is the form: class MyForm(forms.ModelForm): key = forms.CharField() secret = forms.CharField() class Meta: model = MyModel fields = ("key", "secret") def save(self, commit=True): send = super(MyForm, self).save(commit=False) if commit: send.save() return send -

Empty and partial dropdown list displayed when loading data from AJAX call via API; and how to POST data?
I have a Django form on which users will be able to input data about a musical composition. Among the various fields there's also a 'performances' one, which is a formset, with venue, date, notes, and link. The 'venue' field is a select2() dropdown list: if the venue is not already in the database the user must be able to add a new one. I initially thought of giving this possibility by adding a button 'add new venue', which opens a modal containing a mini-form with just one field, where the user can input the name of the new venue. I've achieved this with a XHR call. Nevertheless, what if the user wants to easily change the venue name, or delete it? That's why I thought of using select2()'s tags:true option and use API calls (I'm using tastypie) via AJAX for both GET and POST. My template: [...] <h3>Performances</h3> <table id="performancesnodb"> <tbody id='performancesnodb_body'> {% for formPerformance in form_performances.forms %} <tr id="row-performancesnodb-{{forloop.counter0}}" class="formPerformances"> <td><select class="selectVenue" name="{{ formPerformance.venue.html_name }}" data-thisId="{{formPerformance.venue.id_for_label }}" id="{{formPerformance.venue.id_for_label }}"> <option value="-1">----</option> </select> </td> [... other fields like link, notes] <script type="text/javascript"> $(document).ready(function(){ $.ajax({ url: "http://127.0.0.1:8000/api/venue/", type: "GET", success: function(data, textStatus, jqXHR) { var xdata = data.objects.map(function(item){ return {value: … -

Create sub page in django admin panel for process and show data based on model record id
Pre information: Used Django version: 2.1.1 Used python version: 3 What is there: In the built-in Django admin panel we are able to see the the models and their records, we can click through them in order to do any CRUD actions. E.g: This is the page where we can change the record of modelRecordId: /admin/myApp/myModel/myModelRecordId/change/ What I want to achieve: Now, I want to add another possible subpage next to /change that allows me to output data based on the myModelRecordIdgiven in the url. Basically, if the admin access that url: /admin/myApp/myModel/myModelRecordId/my_view/ I want to be able to process and generate that page for the related myModelRecordId. What I got so far was adding a ModelAdmin model: class MyModelAdmin(admin.ModelAdmin): def get_urls(self): urls = super().get_urls() my_urls = [ path('my_view/', self.my_view), ] return my_urls + urls def my_view(self, request): context = dict( self.admin_site.each_context(request), key='test', ) return TemplateResponse(request, "admin/myModel.html", context) .. with that I was able to achieve that my_view is available via /admin/myApp/myModel/my_view/ what does not bring me that much further, since I want that page to be accessible one level deeper in order to process the given myModelId information. (e.g. request DB with that myModelId and show data) Thanks in …
