Django queryset get all data that pass a selected date
I created an object from a model call Project which look like this : [ { "name": "project A" "start_date": 2019-01-01 "end_date": 2019-02-15 }, { "name": "project B" "start_date": 2019-01-15 "end_date": 2019-02-01 }, { "name": "project C" "start_date": 2019-02-27 "end_date": 2019-03-12 }, ] if I have a date range selector and I select the date from 2019-01-07 until 2019-02-10, and my query look like this model_object = Project.objects.all().filter(start_date__gte=(2019-01-07), end_date__lte=(2019-02-10)) The result of model_object queryset will be : { "name": "project B" "start_date": 2019-01-15 "end_date": 2019-02-01 }, What I wanted now is how can I filter the query in such way where I get all the object that is ongoing in between the date 2019-01-07 until 2019-02-10 which mean the result should also include project A because its still ongoing from 2019-01-01 until 2019-02-15 even though it started before 2019-01-07 Any help is much appreciated thanks. -

How to use Python iteration to read paragraphs, tables and pictures in word？

Overriding ModelForm with widgets
A user has a form where he can save sensitive data. I am capable of crypting this data and store it in the database using modelforms. However, if the user wants to modify this data, it appears in the TextInput from the form. I've read this post, and this one. The answer seems to be there, but I can't manage to suceed in the implementation. Here is what I have: Models class CustomUser(AbstractUser): api_key = models.CharField(max_length=256, default='null') Forms class APIForm(forms.ModelForm): class Meta: model = CustomUser fields = ('api_key') widgets = { 'api_key': TextInput(attrs={'size': 10, 'placeholder': 'Your key'}), } Html <form method="post"> {% csrf_token %} {{ form|crispy }} <button type="submit">Save changes</button> </form> It seems that the form is not detecting the widget, since if I change the value of the attribute size, the form will not change. Am I missing something? Thanks in advance -

Google sign-in using android-studio front-end and django back-end
I am totally new to django and android studio. I am developing an app on android studio and as part of it, I added a Google Sign-in mechanism. The sign-in in the front-end - works just fine, and I'm able to hold the user's TokenId. Here is a quick summary of what I'm trying to do - In my application, I want users to have points that will be saved on the server. to do so, I'm using Google sign in. Now, in the server, I want to have a table that connects each user with his score, so It can be updated according to the user's activity. Now, I want to establish a session with my django server. I read in the django book and all I could find is references to django authentication system - which I don't want to use, as I'm using Google's sign-in. My questions are: I read this (link) and I saw that once I pass the TokenId from the front-end to the server, I need to do some verification - and once I'm done, I hold this: userid = idinfo['sub'] Now, I want to create a table that recognizes the users - do … -

Celery task worker not updating in production
I have set up a django project on an EC2 instance with SQS as broker for celery, running through Supervisord. The problem started when I updated the parameter arguments for a task. On calling the task, I get an error on Sentry which clearly shows that the task is running the old code. How do I update it? I have tried supervisorctl restart all but still there are issues. The strange thing is that for some arguments, the updated code runs while for some it does not. I checked the logs for the celery worker and it doesn't receive the tasks which give me the error. I am running -P solo so there is only one worker (Ran ps auxww | grep 'celery worker' to check). Then who else is processing those tasks? Any kind of help is appreciated. -

Best practice for adding a new item in client
I have a list that the client fetches from the server. The client can add more items, and it's 'auto save' so no need to press a button. My question is how to manage the new item id (can be several). Do I need to immediately go to the server to get a new key? or can I allocate some key Ids (say 0-10) and later in the auto save call the server will know to assign new keys and notify the client?

How to tell to client that Django web application is in healthy state or not (status 200)
I have written a Django web application and also supported REST API to get JSON response. Now I want to write some health endpoint ( some url ) which is when used, my django web application should tell whether or not it is in healthy state. Example, If my Django application is not running ( web server is down ), then if a rest api client tries accessing the health endpoint (URL) and it should get response telling application is not healthy. On the other hand if application is running/up ( web server is up ) then accessing the health endpoint will show message that application is healthy. Is it doable in Django ? Thanks in advance. -

Convert ratings in stars in Django template
I'm working on a project using Python(3.7) and Django(2.1) in which I want to display an average rating returns from a view inside the Django template. Here's What I have tried so far: From models.py: class Gig(models.Model): CATEGORY_CHOICES = ( ('GD', 'Graphic & Design'), ('DM', 'Digital Marketing'), ('WT', 'Writing & Translation'), ('VA', 'Video & Animation'), ('MA', 'Music & Audio'), ('PT', 'Programming & Tech'), ('FL', 'Fun & Lifestyle'), ) title = models.CharField(max_length=500) category = models.CharField(max_length=255, choices=CATEGORY_CHOICES) description = models.CharField(max_length=1000) price = models.IntegerField(blank=False) photo = models.FileField(upload_to='gigs') status = models.BooleanField(default=True) user = models.ForeignKey(User, on_delete=models.CASCADE) created_at = models.DateTimeField(default=timezone.now) def __str__(self): return self.title class GigReview(models.Model): RATING_RANGE = ( ('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('5', '5') ) user = models.ForeignKey(User, on_delete=models.CASCADE) gig = models.ForeignKey(Gig, on_delete=models.CASCADE, related_name='rates') order = models.ForeignKey(Order, on_delete=models.CASCADE, null=True) rating = models.IntegerField(choices=RATING_RANGE,) content = models.CharField(max_length=500) def __str__(self): return self.content From views.py: def home(request): gigs = Gig.objects.filter(status=True).annotate(avg_review=Avg('rates__rating')) return render(request, 'home.html', {'gigs': gigs}) So, now every gig has an average rating and I want to display stars as the rating inside the template. From home.html: {% for gig in gigs %} <div data-marker-id="59c0c8e33b1527bfe2abaf92" class="col-sm-6 col-xl-4 mb-5"> <div class="card h-100 border-0 shadow"> <div style="background-image: url(/media/{{ gig.photo }}); min-height: 200px;" class="card-img-top overflow-hidden dark-overlay bg-cover"> <a … -
Django 2.1 Site With Two (or more) Language
I am currently researching a solution or approach to the following problem. We need a site that will operate in at least two different languages. The site is Django 2.1-based and uses DjangoCMS. It will have a multi-language blog-like capability in which articles will be published in different languages. Videos will also be posted there. We would like to have an ability to post separate content to different (language) sides of the site. The user will be able to select their language preference in the navigation bar and that version of the site will be served to him from there on. It appears that we would like to have to have two different sets of paths along the lines of www.example.com/lang1/* www.example.com/lang2/* That is, each (or most) pages will be present on both language side and the only difference between the paths will be the language prefix. That said, the slugs would need to be in the native language, if that matters at this point. This is a vision, but it is certainly negotiable. While doing the research, I have found questions like this which have been helpful: Django site with 2 languages However, it appears that I am still …
