How to login in django with https/ssl at deploy server
I have django project. It works well on my Mac.But it's not work well on GCP(Ubuntu 17). When I try login from login page. I cant login and authorize. I return same login page. No thing happen. Just reload same page. This site uses Nginx with uWSGI I'm thinking this problem comes from https/ssl settings. If you know how to solve this problem, please let me know. This is my code: urls.py from django.conf.urls import url from django.contrib.auth.views import login, logout_then_login from django.urls import reverse_lazy from . import views from django.contrib.auth import views as auth_views app_name = 'invo' urlpatterns = [ # Login Logout url(r'^login/$', login, {'template_name': 'invo/login.html'}, name='login'), url(r'^logout/$', logout_then_login, name='logout'), ] nginx setting # the upstream component nginx needs to connect to upstream django { # server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 127.0.0.1:8001; # for a web port socket (we'll use this first) } # configuration of the server server { # the port your site will be served on listen 443 ssl; ssl_certificate /etc/letsencrypt/live/tekis.biz/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/tekis.biz/privkey.pem; # the domain name it will serve for server_name tekis.biz; # substitute your machine's IP address or FQDN charset utf-8; # max upload size client_max_body_size 75M; # adjust to … -
Django 2.0 Password Validation
By default in Django 2.0 we get AUTH_PASSWORD_VALIDATORS option with UserAttributeSimilarityValidator MinimumLengthValidator CommonPasswordValidator NumericPasswordValidator So is there any easy way to add extra VALIDATORS like minimum 1 uppercase, 1 symbol, 1 digit, etc. ? In python i can check Using regex import re userPass = 'HelloWorld*123' if re.search('[A-Z]', userPass)!=None and re.search('[0-9]', userPass)!=None and re.search('[^A-Za-z0-9]', userPass)!=None: print 'Strong Password' -
Mysql error while starting Django on eclipse
Hi i'm new to Django framework and want to connect MariaDB. So I added the code below on settings.py DATABASES = { 'default': { #'ENGINE': 'django.db.backends.sqlite3', #'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), 'ENGINE': 'django.db.backends.mysql', 'NAME': 'findworknear', 'USER': 'root', 'PASSWORD': 'root', 'HOST': 'localhost', 'PORT': '' } } However, whenever I tried to run server, all I could see were several lines of error messages. I tried some tips found on stackoverflow. (sudo pip install python-mysql, sudo pip install mysqlclient). But none of them worked.

Implementing Django Form without Model
This is a continuation from last question here Coding mental block with specific Django task The answer was: A pure django solution would be: create a form with three integer fields (say, num1, num2 and result) in your view, populate num1 and num2 with the numbers to be added render the form in your template (num1 and num2 fields should be read only) the user enters the answer in the result field and submits the form in your view, determine whether num1 + num2 == result redirect to a success page if the answer is correct, otherwise redisplay the form However, as I am working through the steps, my form was not being rendered properly. views.py def post_question(request): form = QuestionForm(request.POST) if form.is_valid(): question = Question(question_text = form.cleaned_data['question_text'], MY_FIELD = form.cleaned_data['MY_FIELD'], exam = form.cleaned_data['exam']) question.save() return HttpResponseRedirect('/numbers/') forms.py class MyForm(forms.Form): a = forms.CharField(max_length=20) mat = forms.CharField(max_length=200) html file <form action="{% url 'form_handle' %}" method="POST">{% csrf_token %} {{form.as_p}} <button type="submit">Submit</button> </form> When I load the page all I see is a submit button. As pictured Can someone please advise me where I had gone wrong? -
Django Error Message
I have a case. Once the form is submitted, it has to make a query. If the query exists, it has to send an error message. If the query does not exist, it has to save the data. I have written view as below and it works. But the only issue is that the error message goes like a success message. I have tried placing the query before validating the form, still, it's same. How could I resolve this? def permissionFormView(request): r_form = forms.RoleForm() p_form = forms.PermissionForm() if request.method == 'POST': p_form = forms.PermissionForm(request.POST) if p_form.is_valid(): role = p_form.cleaned_data['role_name'] feature = p_form.cleaned_data['feature'] if models.PermissionModel.objects.filter(role_name=role,feature=feature).exists(): messages.error(request, 'Permission exists.') else: p_form.save() messages.success(request, 'Permission added successfully.') return render(request, 'company_profile.html', {'r_form': r_form, 'p_form': p_form}) return render(request,'company_profile.html',{'r_form':r_form,'p_form':p_form}) Client Side Form Code: <form action="{% url 'permission_form' %}" novalidate method="POST"> {% csrf_token %} <div class="row"> <div class="col"> <label for="r_name"><small><strong>{{ p_form.role_name.label }}</strong></small></label> <p>{{p_form.role_name}}</p> {% for error in p_form.role_name.errors %} <p><small class="alert-danger">{{ error }}</small></p> {% endfor %} </div> <div class="col"> <label for="r_feature"><small><strong>{{ p_form.feature.label }}</strong></small></label> <p>{{p_form.feature}}</p> {% for error in p_form.feature.errors %} <p><small class="alert-danger">{{ error }}</small></p> {% endfor %} </div> <div class="col"> <label for="permission"><small><strong>{{ p_form.permission.label }}</strong></small></label> <p><input type="checkbox" class="form-control" id="permission" name="permission" {% if r_form.role_name.value is not None %} value="{{ p_form.permission.value … -
Makefile for Running Django Backend and React Frontend
I am working on a project which is developed by Django REST Framework and served by React app. There is a partition between the back end and front end. The structure of the path is: Root ├── backend ├── frontend ├── makefile ├── readme.md ├── requirements.pip └── venv Currently, I run the project by opening two different terminals. Then I start the django server first and then start the react app. In terminal 1, I start the django server: cd backend python manage.py runserver In terminal 2, I start the react app: cd frontend npm start So, it is quite irritating to redo these commands each time to run the project. Recently, I have heard about makefile. I think this will reduce the number of commands to start the project. I have created the following makefile: run: python backend/manage.py runserver cd frontend npm start When I write make run it successfully starts the Django server but it does not start the React application. What am I missing here? Can I run the both commands in a single command using make? -
force-download with Django and Vue
I was trying use vue to download file from server when I director visit my backends API, it work well，and I can unzip my file normal. but when I try to download file by axios response, the file can not unzip，and also if I don't set link.download, the filename does not correct.like that here is my vue's api export function packMaterials (context, thesisId, filename) { context.$axios({ method: 'get', headers: getAuthHeader(), url: PACK_URL + thesisId }) .then(function (response) { console.log(response) let blob = new Blob([response.data], { type: 'application/force-download' }) let link = document.createElement('a') link.href = window.URL.createObjectURL(blob) link.download = filename link.click() }) .catch(function (error) { console.log(error) }) } here is my Django API if os.path.exists(file_path): # 返回file with open(file_path, 'rb') as fh: response = HttpResponse(fh.read(), content_type="application/force-download") response['Content-Disposition'] = "attachment; filename={}".format(escape_uri_path(filename)) return response and here is the response data in console.

OperationalError at /app/top/ no such column: app_post.category_id
I got an error,OperationalError at /app/top/ no such column: app_post.category_id . I wrote codes in views.py from .models import POST from django.shortcuts import render def top(request): contents = POST.objects.order_by('-created_at') render(request, 'top.html', {'contents': contents} in models.py from django.db import models class Category(models.Model): name = models.CharField("CategoryName", max_length=100) def __str__(self): return self.name class POST(models.Model): title = models.CharField(max_length=100) text = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) category = models.ForeignKey(Category, on_delete=models.CASCADE, verbose_name="Category") def __str__(self): return self.title First I made POST model and next I did Category model ,then I connected them by using ForeignKey.I think this process causes this error so I run command python manage.py flush --database=default and delete all migration file.However same error happens.I deleted db so I think it solve the error, but I am wrong.How should I fix this?What should I do to fix this? -

Is there a way to view word files locally using office web viewer
I have a word file, and I want to open up that word file for preview/viewing purposes only, not to edit. How could I go by this? I have a Django application and one of the main purpose of the application is to view documents that people upload on the site. However for testing purposes I cannot get to preview documents for reasons I do not know. I am using Microsoft office viewer to view the files. This is my html code in Django: <iframe src="https://view.officeapps.live.com/op/embed.aspx?src=http://127.0.0.1:8000/media/project/1/f73ab109-dcaa-4cc3-bbfc-7121eca10118.doc"> </iframe> And this is was the error displayed in the html: I am assuming that the office viewer is expecting a "real" internet directory and not something locally. -

How to enforce reads from read replica in Postgres using django and or flask?
Is enforcement of a reads from a read replica an application layer task? i.e. I have a Postgres database and I have set up a read replica. On the application side I have two connections one for the "write" database and one for the "read replica" database. In my code if I do a "read" action I use the connection to the read replica. But when I go to insert or update I use the connection to the "write" database a.k.a. master. Is there better with django or flask that this is managed automatically. i.e. I would prefer to avoid specifying directly in code the connection to use and just have django or flask figure it out on their own. -

Django Accepting AM/PM As Form Input
I am trying to figure out how to accept am/pm as a time format in Django using a DateTime field, but I am having some trouble. I have tried setting it like this in my forms.py file pickup_date_time_from = DateTimeField(input_formats=["%m/%d/%Y %I:%M %p"]) with the following data: 12/31/2017 02:40 pm However, I get a validation error when submitting the form: (Hidden field pickup_date_time_from) Enter a valid date/time. I have also tried setting a global variable in settings.py as the documentation states: DATETIME_INPUT_FORMATS = ['%m/%d/%y %I:%M %p'] What does work is if I submit the data without the am/pm, but the output is 2017-12-31 02:40:00+00:00 Any other options? -

Previous search on django search
Is there a way to implement going back to a previous search on a page? Example: I have an index with a search form / filters and I perform a search -> click an item in index -> display "previous search" button on this items detail view. I looked into {{ request.META.HTTP_REFERRER }} but this didn't seem to be working for me for processing the old form data on the GET request (going back to the index page). I had multiple checkboxes able to be selected so these would be added as field=1&field=2& ..... for the different options, but these weren't showing up in the url - in HTTP_REFERRER. I'd also prefer to preserve POST method so I don't have "ugly" urls, but using GET is the only way I see this being feasible. -

celery daeminization w/ Djnago - Please explain step-by-step like I'm 5
I'm new to Python and really trying to learn things as I go. I have a Python script that pulls data from different sites and displays it to the public via a website.
