Ability to find certain pages through search
I want to have a search bar that search all the views that are static and supplies search results for example this page here has the function I need: https://cagenix.com/ . If you click the magnifying glass it opens a search bar and allows you to search all their static pages and supplies the user with results. Is there any way to do this in Django views? -
Django Rest Framework Grouping results by Foreign Key value
I am trying to do a child list model. This model has parent foreign key and child foreign key. What I want to do is to gather the ones with the same parent value under a single group. If the parent 1 has 3 child, the result should look like this: { first_name: "bla bla" last_name: "bla bla" children: [ { first_name: "bla bla"} { first_name: "bla bla"} { first_name: "bla bla"} ] } Is there any way to do this in child list serializer? I just couldn't make it. I want to go to the url address according to the parent value and make a grouping as above. First solution that came to mind is using the related name field. I tried to do this, but I was unsuccessful. I can write similar codes, I have already written for other apps on this project. However, when the subject comes to the list of children, my brain is failing me. I can't find the right thing to do, I can't understand. Models class ChildProfile(models.Model): user = models.OneToOneField( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, primary_key=True, verbose_name=AccountStrings.ChildProfileStrings.user_verbose_name, related_name="user_child") city = models.ForeignKey( City, on_delete=models.SET_NULL, null=True, blank=True, verbose_name=AccountStrings.ChildProfileStrings.city_verbose_name, related_name="city_child_profiles") hobbies = models.CharField( max_length=500, null=True, blank=True, verbose_name=AccountStrings.ChildProfileStrings.hobbies_verbose_name) class ParentProfile(models.Model): … -
Blank page on mobile when Debug is off
I built an app on Django & React which displays a blank page on mobile browsers & Safari (desktop) as soon as I set DEBUG=False in my Django settings.py file. I inspected the browser consoles network tab and noticed that Safari seems to be unable to read my react javascript bundle. I inspected the network tab on Safari with both Debug on and off to see if there are any differences in how the file is served and found this: Debug=False (app not loading) As you can see, the response Content-Disposition is telling me that the file's extension is .js.gz - this ends up showing the "corrupted" version of the file which I linked in the first screenshot. Debug=True (app works as expected) When setting debug to true, it loads a different version of the same file. The filename is slightly different and the file extension is .js I use webpack to bundle these files and a package called django-webpack-loader to inject them into my HTML template. Code in settings.py that might be relevant: # django-webpack-loader if DEBUG: WEBPACK_LOADER = { 'DEFAULT': { 'BUNDLE_DIR_NAME': '', 'STATS_FILE': os.path.join(BASE_DIR, 'webpack-stats.json'), 'TIMEOUT': 10, }, } if not DEBUG: WEBPACK_LOADER = { 'DEFAULT': { … -

Page not updating after adding image to django admin
I've created a model HomeImage. I have FOR LOOP in my template, where I render images to a page from my database. What I did is that you can add images through admin site and my problem is, that after I add image to admin it doesn't render added image/s.

How to set up my Django models for this ManyToMany scenario?
I gather keywords with their monthly values over a period of time. Then I want to relate certain keyword combinations (average the values for example) for certain topics. So here is a basic table structure with some sample data so you can picture what I am dealing with: Table 1 - columns 1,2,3 are "unique together" keyword | location boolean (inUSA true/false) | Date | Value dog | true | 01/01/2020 | 10 dog | true | 02/01/2020 | 20 dog | true | 03/01/2020 | 10 dog | false | 01/01/2020 | 10 cat | false | 01/01/2020 | 10 Table 2 Topic | has many keywords | extra info dogs in USA | should reference 3 entries dogs everywhere | 4 entries dogs and cats outside of USA | 2 entries dogs out of USA | 1 entry cats out of USA | 1 entry Keywords can belong to many topics, topics can have many keywords. Can a simple ManyToMany relationship between 2 models work? Or do I need something more complicated? I tried setting it up with 2 models, but having 3 primary keys for table1 (dog,inUSA,date) gets too complicated and I don't know if Django can … -
Django form field validation not working and no errors

How to fix 404 error on DJANGO for external URL

How do we combine multiple tables to create a report table displaying all the columns with an auto-incrementing, regex defined ID of its own?
I have 3 models: class Student(models.Model): roll_number=models.IntegerField(primarykey=True) name=models.CharField(max_length=50) email=models.EmailField(max_length=60) city=models.CharField(max_length=20) class Course(models.Model): roll_number=ForeignKey(Student, on_delete=CASCADE) course=ForeignKey(CourseChoices, on_delete=CASCADE) class Fee(models.Model): roll_number=ForeignKey(Student, on_delete=CASCADE) total_fee=models.DecimalField(max_digits=7, decimal_places=2, default=0) discount=models.DecimalField(max_digits=5, decimal_places=2, default=0) Final_amount=models.DecimalField(max_digits=5, decimal_places=2, default=0) Amount_received=models.DecimalField(max_digits=5, decimal_places=2, default=0) Balance=models.DecimalField(max_digits=5, decimal_places=2, default=0) batch=models.CharField(validators=[batch_pattern]) Now, whatever data these tables hold, I want to display them together as: Track ID--Roll No.--Name--Email--City--Course--Total Fee--Discount--Final Amount--Amount Received--Balance--Batch These are the Column heads I want. The 'Track ID' should be the report's own primary key which I want to define using regex. Also, I want every instance to appear in this report with different Track ID. For example, if a student pays a partial fee, it will get recorded in a row with a Track ID. Whenever he/she pays the rest of the amount, should get recorded with the relevant Track ID as per its place in the sheet. I hope I'm explaining well what I intend to achieve here. If I'm not clear, kindly let me know and I'll explain everything with an example or something. Hope I get some help on this here. -
User-specific home page Django
I am trying to create a user-specific home page for my Django site (i.e., go directly to the logged-in user's page when the site is loaded). I am having trouble figuring out how to add the username to the URL path from the get-go. This is how I've typically created the path to the home page: urlpatterns = [ path('admin/', admin.site.urls), path('', include('blog.urls')), But essentially what I think I want to do is this: urlpatterns = [ path('admin/', admin.site.urls), path('<username>/', include('blog.urls')), So that the default home page when I run the server would be something like this : http://127.0.0.1:8000/someusername Is there a way to access the logged-in user by default automatically? -

I am using Django signals to trigger a task (sending mass emails to subscribers using Django celery package)when an admin post a blogpost is created from Django admin.

form.is_valid(): -- with ModelForm instead of form- User specific data - Django
So I am integrating user-specific data in my Django website and I have gotten it to kind of work. Right now it is working on a model called ToDoList with one field called "name" and a (form.Form) in my forms.py file.

Django LOGGING exception handling

Virtualenv for django in VS Code not working, What am I doing wrong?
I've been following a tutorial on how to start using django and creating a virtual env on VS Code, but it doesn't work.. For what it shows in the tutorial, it's supposed to create a folder called ".vscode" with a json file inside called "settings.json" that contains the python path to the python interpreter.. But in my case, none of those files appear.. I THINK there might be sth wrong with the path where it creates the virtual env, but since I'm pretty new at this, I can hardly say.. This are the steps I followed: C:\Users\Usuario\Desktop\Andres\Programación\5. Prácticas\3. PYTHON>cd DJANGO C:\Users\Usuario\Desktop\Andres\Programación\5. Prácticas\3. PYTHON\DJANGO>mkdir storefront C:\Users\Usuario\Desktop\Andres\Programación\5. Prácticas\3. PYTHON\DJANGO>cd storefront C:\Users\Usuario\Desktop\Andres\Programación\5. Prácticas\3.

django social share button icons
I'm trying to add the functionality to share a workout post to social media, and found that the django-social-share package is the best. Everything works, but I'm curious how to add an icon over the link, as it currently looks like Post to Facebook! which is very bland. I've seen examples of adding CSS, but since the package works like {% post_to_facebook object_or_url "Post to Facebook!" %} I'm not sure how you could target that with CSS. Any help is appreciated. -

Django Admin - dynamic select options with foreignkey and manytomanyfields
Here the supplier is related to Supplier model (ForeignKey) and substrate is with Substrate (ManyToManyField). The main model here is SupplierInfo from which we can filter suppliers and get their respective substrate. When ever admin clicks on the dropdown of Arrival_supplier and, SupplierInfo_substrate should be filtered with the supplier name and should be able to receive SupplierInfo_substrate inside Arrival_substrate. The Arrival model, where the filtered SupplierInfo_substrate should be saved. class Arrival(models.Model): submitted_on = DateTimeField(auto_created=True, null=True, blank=False, editable=False) edited_on = DateTimeField(auto_now_add=True) submitted_by = ForeignKey(get_user_model(), on_delete=models.SET_NULL, null=True) supplier = ForeignKey(Supplier, null=True, on_delete=models.SET_NULL) arrival_date = DateField(auto_now_add=True, null=True, blank=False) substrate = ManyToManyField(Substrate, blank=True) The Substrate and Supplier models, which are connected to Arrival and Supplier. class Substrate(models.Model): name = CharField(max_length=299, unique=True, null=True, blank=False) class Supplier(models.Model): name = CharField(max_length=299, unique=True, null=True, blank=False) The SupplierInfo model, from which supplier and its substrate should be filtered. Note: One supplier can have multiple substrates. Simply, filtering supplier returns multiple query set each with a different substrate (ForeignKey) name. class SupplierInfo(models.Model): supplier = ForeignKey(to=Supplier, on_delete=models.SET_NULL, null=True, blank=False) substrate = ForeignKey(to=Substrate, on_delete=models.SET_NULL, null=True, blank=False) mushroom = ForeignKey(to=Mushrooms, on_delete=models.SET_NULL, null=True, blank=False) weight = FloatField(null=True, validators=[MinValueValidator(0.9)],blank=False) yield_min = FloatField(null=True, validators=[MinValueValidator(0.9), MaxValueValidator(100)]) yield_max = FloatField(null=True, blank=True, validators=[MinValueValidator(0.9), MaxValueValidator(100)], ) status = BooleanField(null=True)
