Djanog save a model in admin.py
I need to save a parameter(specs which is a dictionary) in Estimate model in django's admin.py. Earlier I used signals but that did not appear to be a wise option. I have below admin.py and here I want to update Estimate's specs field by merging this field with Environment's specs. How can I achieve that? I am still learning Django. I have understood that in the Django admin, when I deal with Estimate model, I get response from Estimate and EstimateAdmin class. At the same time I also have Environment whose foreign key is Estimate and in the Django Admin's Estimate model, Environment is an object. I tried Estimate_specs = Estimate.objects.all() but need to filter the specs on the basis of current estimate and Environment_specs = Environment.objects.all() but again this needs to be filtered with specs on the basis of current estimate. I am not able to figure out how to get this working. class EnvironmentInlineAdmin (admin.TabularInline): model = Environment ... class EstimateAdmin (CommonAdmin): ... admin.site.register(Estimate,EstimateAdmin) class EnvironmentDetailsInlineForm(forms.ModelForm): class Meta: model = EnvironmentDetail fields = ['item_name','qty'] show_change_link = True class AddEnvironmentDetailsInlineForm(forms.ModelForm): ... class EnvironmentDetailsInlineAdmin (admin.TabularInline): ... class AddEnvironmentDetailsInlineAdmin (admin.TabularInline): model = EnvironmentDetail fields = ('item_name','item', 'qty', ) form = AddEnvironmentDetailsInlineForm … -

What's the relationship between csrfmiddlewaretoken and csrftoken?
I was working with Django to create a website and got some questions about CSRF. I use django.middleware.csrf.CsrfViewMiddleware and add <form action="" method="post">{% csrf_token %} in my POST form. And when I test the website: GET / HTTP/1.1 Host: 123.207.137.168:8000 Then, I got cookies Set-Cookie:csrftoken=Ev8veOH89vFDnG3a0GJUsMXA1oGZXxqXRw2nFWiKrvZ9UE10niTlZCiOxdnoKfTv; expires=Thu, 27-Dec-2018 06:37:41 GMT; Max-Age=31449600; Path=/ But in the html: <input type='hidden' name='csrfmiddlewaretoken' value='JswHLk4fNpxHkh0OObD1uKiOxSDUzkMDWtqzcsFR5pRdRfYEbNNs1AD23Hkjm2fb' /> So I was wondering why the csrftoken and csrfmiddlewaretoken is different and how did the server use these two value to valid if the request is from the users or hackers? -

How to upload multiple files individually with additional data
I am using blueimp's fileupload. The data is sendable if I do not try to send an additional input on submit. I am trying to upload files with a title following this pattern: user clicks a "select HHs" button to select files After the files are selected and opened, user sees every file listed in rows with a "title" input box and a "submit" button. User types in value for the "title" box and hits "submit" button to send to backend. After #3, I keep getting a 403 sent back a "Forbidden (CSRF token missing or incorrect.)" on the server side (django). Why am I getting this error message and how do I solve this issue? I've replaced data.formData with a simple object to test what I'm trying to accomplish below. upload.js file: $('#fileupload').fileupload({ formData: {title: 'test'}, dataType: 'json', ... add: function (e, data) { var convertElem = $('<input type="submit"/>').click(function() { data.formData = {"title":"test"}; data.submit(); }); ... data.context = $(outerElem) ... } }); upload.html: <button>Select</button> <form id="fileupload" data-url="{% url 'file-upload' %}" enctype="multipart/form-data" data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'> <input id="fileupload-files" type="file" name="file" multiple> </form> -

Wagtail can't access images on S3 - I/O operation on closed file
I'm trying to get Wagtail to store and serve images from an AWS S3 bucket. I have followed the instructions and have it working great in a test environment, however when I switch to the Production Database and Bucket, I run into problems using the Admin and occasionally the frontend too. I have: boto3==1.4.8 botocore==1.8.1 wagtail==1.10c1 python 2.7 What I do: I go to /admin/, browse Images, it shows a list of image thumbnails (so far so good) I click on one of them and I get a Django error: ValueError at /admin/images/4236/ I/O operation on closed file The exception says: /usr/lib/python2.7/StringIO.py in tell _complain_ifclosed(self.closed) ... /usr/lib/python2.7/StringIO.py in _complain_ifclosed raise ValueError, "I/O operation on closed file" ...

They are all in the one collection. Is there any way to increase the time out on this operation so that it doesn't time out?

Sort and set REST API data into a new list
I'm trying to create a report table based from an API, but the API currently is not sorted as I wanted it to be and I'm not sure how to rearrange it. Here's an example of how the API that look like this : [ { "task": { "id": 2, "name": "Texturing", }, "assign_to": { "id": 1, "official_name": "Roy Harper", }, "duration": 3.0, }, { "task": { "id": 4, "name": "Lighting", }, "assign_to": { "id": 3, "official_name": "Donna Troy", }, "duration": 4.0, }, { "task": { "id": 8, "name": "Rendering", }, "assign_to": { "id": 1, "official_name": "Roy Harper", }, "duration": 7.0, }, { "task": { "id": 11, "name": "Coloring", }, "assign_to": { "id": 3, "official_name": "Donna Troy", }, "duration": 5.0, }, { ] What i trying to achieve now, is an API list that centralize on the assign_to field and also set the list so it only populate the same person once. here's how the desired output that I trying to achieve : [ { "assign_to": { "id": 1, "official_name": "Roy Harper", }, "total_task"[ "task":{ "id": 4, "name": "Lighting", }, "duration": 3.0, "task":{ "id": 8, "name": "Rendering", }, "duration": 7.0, ], }, { "assign_to": { "id": 3, "official_name": "Donna Troy", … -
How do I handle multiple choice using Django?
Suppose I have a model with a multiple choice field and 4 options. This would be passed to the template and rendered on the HTML page. I want the user to select an option, and then process the option and return either "Correct" or "incorrect". I'm not too sure how to go on about starting this, any help is so much appreciated. -

Unable to save response data to instance's fields; other data in same block is saved correctly (Django/Celery)
I'm running a task to create an account on a third-party service and save relevant data from that service's response to my profile object. The data is getting returned correctly but not being properly saved on the object. Relevant code: # payload is generated in helper method. if that was the point of # failure, i'd see an error result = self.third_party_client.post(self.creation_endpoint, payload) json_result = result.json() if json_result.get('Error') != 'SUCCESS': # Account Creation Failed. error is handled. else: # Currently I log this on our staging server to make sure # the data's coming back properly; it is returned as expected self.logger.error('CoreCard Account Created. Data: {}'.format(json_result)) profile = user.profile profile.account_number = json_result.get('AccountNumber') profile.card_number_last_four = int(json_result.get('CardNumber')[12:]) profile.customer_id = json_result.get('CustomerID') profile.account_creation_datetime = datetime.datetime.utcnow() profile.save() So if I then query this profile instance, it has the account_creation_datetime value as expected, but the other fields are blank. I've checked the logs and the json_result values are all correct. Now here's where it's a bit weird. Where I think it's actually failing is the celery task that calls the utility that runs this bit of code. If I run this utility manually, the fields are saved properly. If I run it as part of our … -
Django raising ValueError: invalid literal for int() with base 10 on POST
Django is consistently throwing a ValueError on every POST request to the server. From cruising around forms and SE, it seems like this an issue with my Django models. However, I'm not sure why the models would throw this error or why they would be called by Django since this is thrown in a POST event.
