Django 2 Bootstrap4 form validation style
I’m trying to incorporate the ‘red’ ‘green’ bootstrap validation feedback, but I just can’t get it to work. I’ve tried different combinations of classes, but I’ve never gotten it to show green on is_valid, I can’t remember if my error messages displayed correctly either(since deleted-wasn’t sure if they were messing with it). Form.py class EmployeeNameForm(ModelForm): class Meta: model = CustomerEmployeeName fields = [ 'employee_choices', 'first_name', 'middle_name', 'last_name', ] widgets = { 'employee_choices': Select( attrs={'class': 'form-control', }), 'first_name': TextInput( attrs={'class': 'form-control', 'placeholder': 'First', }), 'middle_name': TextInput( attrs={'class': 'form-control', 'placeholder': 'Middle (optional)', }), 'last_name': TextInput( attrs={'class': 'form-control', 'placeholder': 'Last', }), } View.py def create_employee_profile(request): if request.POST: name_form = EmployeeNameForm(request.POST) if name_form.is_valid(): new_name_form = name_form.save() return redirect(new_name_form) else: return render(request, 'service/template_create_or_update_profile.html', {'name_form': name_form} ) else: name_form = EmployeeNameForm( initial={'employee_choices': 'E'} ) return render(request, 'service/template_create_or_update_profile.html', {'name_form': name_form} ) Base.html {% load static %} <!DOCTYPE html> <html lang="en" <head> <!-- Required Meta Tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" integrity="sha384-9gVQ4dYFwwWSjIDZnLEWnxCjeSWFphJiwGPXr1jddIhOegiu1FwO5qRGvFXOdJZ4" crossorigin="anonymous"> <!-- Jquery link --> <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script> <!-- Popper link --> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js" integrity="sha384-cs/chFZiN24E4KMATLdqdvsezGxaGsi4hLGOzlXwp5UZB1LY//20VyM2taTB4QvJ" crossorigin="anonymous"></script> <!-- Bootstrap 4 link --> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js" integrity="sha384-uefMccjFJAIv6A+rW+L4AHf99KvxDjWSu1z9VI8SKNVmz4sk7buKt/6v9KI65qnm" crossorigin="anonymous"></script> <!-- static.style.css --> <link rel="stylesheet" href="{% static 'style.css' %}" type="text/css" … -

Order queryset by alternating value
I have the following model: class Entry(models.Model): name = models.Charfield(max_length=255) client = models.Charfield(max_length=255) client is the name of the client as could have values like facebook, google, and so on. Is it possible to order the queryset so that the result is alternating the values of client? What I expect is something like this: Entry.objects.order_by('alternate client') --> | client | name | | google | robert | | facebook | linda | | google | kate | | facebook | jack | | google | nina | | facebook | pierre | I am using django2.x and postgres if that helps. -
Django Table-based Form - Update Processing
Apologies if this is a silly question but I have been hunting for a solution and I am stuck! In my views.py I pass a nested list with data from an API call. That data is then iterated over in the template and displayed in a table. I want the user to be able to modify certain fields (text fields) in the table and to post the updates which will then only update the certain fields that have been changed. Can someone suggest how I might do this? {% for interface in intData %} [...] <td><select name="vlan"> {{ interface.4 }} {% for dictionary in vlanData %} {% for vlan, description in dictionary.items %} {% if vlan == interface.4 %} <option value="{{ vlan }}" selected>{{ vlan }} - {{ description }} </option> {% else %} <option value="{{ vlan }}">{{ vlan }} - {{ description }} </option> {% endif %} {% endfor %} {% endfor %} </select></td> -

ValueError when executed in separate thread
I have a function that processes a zip file of csvs in my Django application. I call the function after a button press when rendering the view by creating a new thread and sending the function as the run method. Here is the function I want to call: update_db.py def upload_files(csv_files): conn = sqlite3.connect('/path/to/db.db') c = conn.cursor() for csv_filename in csv_files.namelist(): if csv_filename.endswith('.csv'): csv_file = csv_files.open(csv_filename) # extract team name from csv_file string, remove whitespace table_name = csv_filename.rsplit('/',2)[1] table_name = re.sub('[^\w+]', '', table_name) try: df = pandas.read_csv(csv_file, error_bad_lines=False) df.to_sql(table_name, conn, if_exists='append', index=False) ##do some stuff except pandas.errors.EmptyDataError as ex: print(str(csv_file) + ' was empty; continuing...') continue; conn.commit() conn.close() The problem is that the function runs perfectly fine if I call it in views, but if I try passing it to a thread it doesn't. This is what I have in the calling environment: def upload(request): if request.method == 'POST' and request.FILES['myfile']: myfile = request.FILES['myfile'] if str(myfile.name).endswith('.zip'): unzipped = zipfile.ZipFile(myfile) # If I uncomment this line, it doesn't throw an error #upload_files(unzipped) # When these lines execute, I get an error t = threading.Thread(target = upload_files, args = (unzipped, )) t.daemon = True t.start() return render(request, 'webapp/upload.html', { 'success': True }) … -
Django signals on Many-to-Many change
I have 3 models: class Product(TimeStampedModel): category = models.ForeignKey('Category', related_name='products', to_field='category_name') brand = models.ForeignKey('Brand', related_name='products', to_field='brand_name') class Brand(models.Model): brand_name = models.CharField(max_length=50) categories = models.ManyToManyField('Category', related_name='categories') class Category(models.Model): category_name = models.CharField(max_length=128) I want to update Brand-Category M2M relationship after I change Product.category. I try to connect the signal m2m_changed, like it is described in the docs: @receiver(m2m_changed, sender=Brand.categories.through) def category_changed(sender, **kwargs): print("Signal connected!") Also I have registered a signal in the apps.py in project_folder: def ready(self): from my_app.signals import category_changed But the problem is - this code doesn't have any effect. I change the Product.category - and doesn't see any prints. How should I fix it to make it work? -
Success message in Django
In my django app I am taking form input.Once that form is validated I am displaying a success message with help of Django Message Framework. Current State I am able to display a success message in the template after submission of form when I redirect it to same url(The url of the form itself) My views.py if form.is_valid(): form_data = form.save() messages.success(request, 'Submited Successfully') return redirect('form-url') What I want Once the form is submitted I want to display a success message on the same page(form-url) and then I want to redirect to a new url list-of-submitted-forms. For that I did something like this to my views.py if form.is_valid(): form_data = form.save() messages.success(request, 'Submited Successfully') return redirect('list-of-submitted-forms') The problem I am facing I am redirecting to a new url.But without getting success message on the form-url page.Also again when I go to form-url page(By clicking a button which redirects to that url) the message of 'Submited Successfully' is shown -
Read only permission to a specific group in admin panel django
I want to give a permission that only user can see the existing entries in a model without edit/change right for a specific group. I tried to add custom permission to provide this but when I do not add the change permission to a user who belongs the group for a specific model, because I do not want to be changed an entry in the model from a person that belongs the group, at that time the model that I did not give change permission turns not to be clickable models therefore, existing objects can not be seen by clicking. How can I provide this feature that a person who belongs a group, only can see the entries of the model without change permission in admin panel. Thanks in advance. -
API architecture for Long time taking process
I don't know is this the right place to ask or not, please pardon me in advance. I have developed the API using DRF but facing the major performances issue. Here is what the scenario is: I am using DRF. Our API call is growing towards 5k per day. Each API call is taking 3 to 10 minutes of time while responding ( as It creates upto 300 pdf label unique format) I am using uwsgi( many worker) now with the Apache. We have implemented the caching but not able improve very much performances level. Primary query: Shall we use gunicorn instead of uwsgi? What about message/ job queue? Is this work. My current server RAM is only 32 GB. Shall I have to increase this if yes how much ( we personal don't want to go for vertical scaling) Please suggest the approach, first time I am handling such level of performance issue. I am very optimistic about message/ job queue and gunicorn. -

upgrade to django 1.11.12 error in models/manager.py contribute_to_class
I haven't touched a project in a long time and realized I upgraded my django to version 1.11.12. Trying to re-run project (runserver) and found several out of date packages (easy-thumbnails and psycopg2). Ran pip install upgrade on those. Now when I run, I get the following error and it seems like it is coming form my models? Not sure what it is telling me though or the proper course of action.

how to pass dates in django
I am a Django newbie and am stuck on a small problem. I am trying to build a view where the user enters a from and to date and I need to pull records from my database according to these dates. I have worked out how to pull records without the user input dates(I tested using system dates, used deltas according to the documentation listed on the official website and i understood it) however am stuck now on how to get them as a user input. Here are a few relevant details of my project: models.py contains a lot of fields but here is the date field entry: date = models.DateField(auto_now_add=True) This entry defines the date the record is created. forms.py: I am using an unbound form(not linked to the model created in models.py) and am using the Jquery plugin listed here in a simple html page to show the from and to date. As a result the dates are passed as plain text in the form according to the documentation listed. The only way I know on how to get a user input is through a form(bound or unbound) which usually ends up as a POST request passing data … -
Populate django table column across multiple levels of foreign keys

Different SESSION_COOKIE_AGE for Different Domain or APP
I have 2 app in one django project. I allow two Domain(e.g. aaa.com & bbb.com) to access my django project. (Actually, aaa.com to app A, bbb.com to app B). (There is some reasons that I want to create 2 app in 1 project.) And I want to set different SESSION_COOKIE_AGE for these 2 domains. So I'm thinking about these solutions... (Solution A) aaa.com - SESSION_COOKIE_AGE = 10 (domain & age are just an example) bbb.com - SESSION_COOKIE_AGE = 20 or (Solution B) App A - SESSION_COOKIE_AGE = 10 App B - SESSION_COOKIE_AGE = 20 Is django support it? If NOT, Since I use this code to create a cookies in views.py for App A, request.session._get_or_create_session_key() request.session.modified = True Can I specific cookies age in views.py which overwrite the setting in settings.py?

Dockerfile: FROM python:3.6.5-jessie MAINTAINER example-user RUN apt-get update \ && apt-get install -y vim RUN mkdir require COPY ./requirements.txt require/requirements.txt RUN pip install -r require/requirements.txt EXPOSE 8000 requirements.txt: Django==2.0.2 As above, I made a image that has name sample-image Next, I runned a container from sample-image like, docker run -ti --name sample_django -p 8001:8000 sample-image /bin/bash And on container bash, I commanded like, root@4a947abf5ce5:/# mkdir startdir && cd startdir root@4a947abf5ce5:/startdir# django-admin startproject sample . root@4a947abf5ce5:/startdir# python manage.py runserver it returned it: Performing system checks...

May 01, 2018 - 12:44:45 Django version 2.0.2, using settings 'sample.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C. Because I set -p 8001:8000 on running container, I found this page in browser( 127.0.0.1:8080), but it did returned it: QUESTION: How can I set port on container correctly? Or is there anything i missed? -
Django: Why is console email backend not sending emails?
I'm trying to make an app to reset user password via email. I'm using the Django by Example book chapter 3, and also took guidance from this site: https://simpleisbetterthancomplex.com/tutorial/2016/09/19/how-to-create-password-reset-view.html Settings.py contains the following line: EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' together with the required email settings. I get to the password_reset view, enter dummy mail, click send, which finally brings me to the password_reset_done view. Below is the console output: C:\PythonProjects\by-example-bookmarks>python manage.py runserver Performing system checks... System check identified no issues (0 silenced). May 01, 2018 - 21:13:39 Django version 2.0.4, using settings 'bookmarks.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CTRL-BREAK.

What could be the cause of the failure to simulate sending email? Environment: Windows 7, on CMD console, under pipenv shell
