I have a djongo engine based google authentication applications My views.py renders the homepage, without passing any arguments: return render(request=request,template_name="mainapp/homepage.html") And homepage.html looks like: <html> <head></head> <body bgcolor = "green"> <p>THIS IS THE HOMEPAGE</p> {% if user.is_authenticated %} <p class="display-4">Hello, {{ user.username }} you are signed in</p> <a href="/account/logout">Log out</a> {% else %} <a href={% url "social:begin" "google-oauth2" %}>Login with Google</a> <p>Not signed in</p> {% endif %} </body> </html> Yet after the user logs in it shows the correct username( not that of the admin). -
How to call function if http request is POST in Django views and pass new submitted file name to function call?
I'm working on web application in which user upload a video and we perform speech recognition on it and then translate its text in another language.So, if the request is POST then we call that function which perform these functionalities and if request is GET it should not call that but in my case,on POST request, function execute first and then POST request is submitted.And it perform functionality on the last video in database. It gives the same result even if I put function call at the end of POST request condition statement and if I put function call out of POST request condition the function call on every reload of page which is not required and I don't know other ways how to solve this problem.

django left outer join filter non-matching records
The goal is to find out if a Survey Response doesn't have current answers for all top level questions. This could be done by getting all top level questions for the Response, and then filter out the questions which don't have current answers. I can write this in SQL but is there a way I can implement this using django's QuerySet interface? Models class Survey(Model): ... class SurveySection(Model): survey = ForeignKey(Survey, related_name='survey_sections') class SurveyQuestion(Model): survey_section = ForeignKey(SurveyQuestion, related_name='survey_questions') parent = ForeignKey('self') #questions can be nested class SurveyResponse(Model): survey = ForeignKey(Survey, related_name='survey_responses') class SurveyAnswer(Model): survey_response = ForeignKey(SurveyResponse, related_name='survey_answers') survey_question = ForeignKey(SurveyQuestion, related_name='survey_answer') SQL This should find all the top-level questions for the Survey the Response is for, getting the current answers that match those questions and removing the questions that don't have answers. select * from survey_surveyquestion question join survey_surveysection section on section.id = question.survey_section_id join survey_survey survey on survey.id = section.survey_id join survey_surveyresponse response on response.survey_id = survey.id left outer join survey_surveyanswer answer on answer.survey_question_id = question.id and answer.is_current = true where response.id = 16 and answer.id is null and question.parent is null -
Is there any way to retrieve Objects from ManyToManyFields in the order they were added?
I have a bunch of Recipes and would like the User to have the option to save the ones he likes. I originally made it with a ManyToManyField on the Recipe model to to the User model but the problem was i wasn't getting them back in order that they were saved. Is there any way to do this? If not, what should i do instead to be able to keep the order? Make a third model with a date field and link the two? Seems like a bit of a waste. Any help would be nice. Thank you -

Django model.field validators don't execute for required Boolean fields
My use case: I have a Yes/No question the user must answer, but they may answer it yes or no. I don't want to supply a default because I need the user to actively select their answer. If they do not select an answer, I want a form validation error, like "This field is required". I know that could store this in the DB as a CharField, but I'd prefer to store it as a required BooleanField. The issue appears to be that the form validation logic does NOT enforce required=True for Boolean fields, nor does it call the model field's custom validators when a value of '' is returned in the POST data. My setup: boolean_choices = ( (True, 'Yes'), (False, 'No'), ) def boolean_validator(value): if value is not True and value is not False: raise ValidationError("This field is required.") class Item(models.Model): accept = models.BooleanField( choices=boolean_choices, validators=[boolean_validator] ) class ItemForm(ModelForm): class Meta: model = Item fields = ['accept'] A complete, working demo of the issue is here: https://repl.it/@powderflask/django-model-form-validators Reproducing the issue create or edit an item, and set the 'accept' value to None ("-------") --> save will crash - notice form.is_valid() passed, crash is in form.save() --> notice that … -
Swal.fire opens unclicable modal (behind html body)

I've tried to replace some codes on the source code, with no luck. Z-index seems to have no effect on this, and the target object that loads the div is not trivial.

Error when making a POST Request in C# to Django REST API
I would like to make a POST Request to a Django REST API. My data (a Json string) lives in a C# application. I am using this snippet: var httpWebRequest = (HttpWebRequest)WebRequest.Create(myurl); httpWebRequest.Method = "POST"; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = "{\"a\":\"sun\", \"b\":\"moon\"}"; streamWriter.Write(json); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); } Unfortunately, I am getting this error at the 'var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();' line : System.Net.WebException: 'The remote server returned an error: (405) Method Not Allowed.' I have also checked the logs of the Django API, it is Django that is throwing the 'Method Not Allowed' error. After doing some research, it looks like it is caused by the fact that POST is not allowed in my Django REST application. I have been able to issue GET requests with no problem. For this, in my django REST framework application, I use a retrieve() function inside my views.py file. I also happen to have a create() function in the same views.py file. I thought this function would be able to handle the POST request. However, it does not look like I am even able to get to … -
Returning empty queryset when used __startswith(or similar kind) while querying mogodb through parsepy
I am accessing mongodb through parsepy in my django application. I have a name field in my db collection. I'm tying to get those name fields which match my query string. For example, if I have these values--> food, folk, form, fill, filled, dust If I query fo I should get food, folk, form. If I query fi I should get fill, filled I found that CollectionName.Query.filter(name__startswith=query) could do that. But unfortunately that is giving me empty queryset. I tried it with CollectionName.Query.filter(name=ExactNameInDB) like CollectionName.Query.filter(name='food') and it returned me the collection object with that name. I even tried name__contains as keyword argument but that didn't work. This one is bugging me since a long time. Please help me. If you think that this explanation isn't enough, I can elaborate the context more. Thanks in advance :) -
Add task from web interface without restarting celery - django

Django filtered queryset in foreignkey lookup
I have a standard model with a foreignkey, in this case from biology: Seed to Taxon. The taxon model includes both Animal and Plant Taxon, and has a category column which is either zoology or botany When I add a new Seed I get the expected dropdown list, but it supplies the zoology and botany options. How do I filter it so only the botany options are shown? I'm assuming this filter can be applied somewhere in the model? I've tried adding .filter() and .exclude() but they do nothing here. class Taxon(models.Model): taxon_id = models.AutoField(primary_key=True) taxon = models.CharField(max_length=50, blank=True, null=True) common_name = models.CharField(max_length=50, blank=True, null=True) taxon = models.CharField(max_length=50, blank=False, null=False) genus = models.CharField(max_length=50, blank=True, null=True) category = models.CharField(max_length=50, blank=True, null=True) # family_name = models.CharField(max_length=50, blank=True, null=True) def __str__(self): return str(self.taxon) class Meta(): managed=False db_table = 'kap\".\"taxon_manager' ordering = ["genus","taxon"] verbose_name_plural = "taxon" class Seed(models.Model): seed_id = models.AutoField(primary_key=True) fraction_id = models.ForeignKey(Fraction, db_column='fraction_id', blank=True, null=True, on_delete = models.PROTECT) taxon_id = models.ForeignKey(Taxon, db_column='taxon_id', blank=True, null=True, on_delete = models.PROTECT, related_name='seed_taxon') weight_type = models.CharField(max_length=50) weight = models.DecimalField(max_digits=10, decimal_places=3) quantity_type = models.CharField(max_length=50) quantity = models.IntegerField() def __str__(self): return str(self.taxon_id) class Meta(): managed=False db_table = 'kap\".\"seed' ordering = ["taxon_id","fraction_id"] verbose_name_plural = "seeds" -
How to get the info parameter which is sent to resolver in tests
I want to test test a function that checks if a field is requested by the query: def field_in_query(field, info): fragments = {} node = ast_to_dict(info.field_asts[0]) for name, value in info.fragments.items(): fragments[name] = ast_to_dict(value) while node.get('selection_set'): for leaf in node['selection_set']['selections']: if leaf['name']['value'] == field: return True else: node = fragments[leaf['name']['value']] if leaf['kind'] == 'FragmentSpread' else leaf return False but i don't know how to get the info parameter. Is there any way to do it?
