Python/Django Comparing two float values leads to TypeError: Can't convert 'int' object to str implicitly
I have the following REALLY! strange behavior when i run my functional tests with selenium. I have a javascript that populates an input field within selenium i check for the correct values in that input field which looks like this. The test runs as a class of StaticLiveServerTestCase # Values to compare against lng= 8.63259210000001 # Get the value attribute of the field lng_field = float(self.browser.find_element_by_id('id_lng').get_attribute('value')) # if i use pdb.set_trace() at this position i can do # all the following operations without any problems # When i do any of the following i get an error message mydiff = abs(lng_field-lng) # or lng_field==lng Or any other Operation where there is a comparison or calculation involving lng and lng_field i get the following error: Traceback (most recent call last): File "...", line XXX, in mytest mydiff = abs(lng_field-lng) TypeError: Can't convert 'int' object to str implicitly however everything works within the console when i use pdb.set_trace(). Even when i convert both values to strings and only use the first 5 (mystring[:5]) characters within the string the code line with the comparison leads to the error stated above. The comparison is not even failing, there is just no comparison during runtime β¦ -

Django OAuth Toolkit: do not get refresh token when using 'client-credentials' authorization grant type
I am implementing an OAuth2 authentication system for my Django application. Everything works fine and I am able to get and use access tokens. However, I got the following problem: When using 'Resource owner password-based' authentication grant type I am able to get refresh_token. But when I register my application with 'client credentials' grant type, it sends me only access_token but not refresh_token. Is there any way to get refresh_token as well? Thanks in advance -

django viewflow without gui
I'm using Django Viewflow like a flow engine without gui. Can anyone post an example for creating a process and flow management programmatically? I do not understand how to manage the flow completely from django code (eg from a test class) without a frontend. Do I need to create a flow instance first?

FileNotFoundError: [WinError 3]
I'm on a Django project which i will scrape some data from various websites. I will use Scrapy to do that. I also found a plugin for Scrapy; Django Dynamic Scraper. I am constantly getting errors when i try to install packages (maybe because i am still using win7 and yes i am drawing figures on my cave's walls).

Create multiple new objects in bulk in Django
I have this model: class School(BaseModel): name = models.CharField(max_length=256) I want to create a form where user can create multiple schools at the same time. I know that there is inlineformset_factory for such cases and all discussions I found online related to creating multiple children of a parent. But in my case I just need multiple parents. I tried to use formset_factory SchoolFormSet = formset_factory(SchoolForm, extra=5) which renders the form properly, but form_valid method is never called and instead form_invalid is called with an error indicating that I did not fill in 'name'...which is not true. This is my form: class SchoolForm(forms.Form): name = forms.CharField( widget=forms.TextInput(attrs=dict( placeholder=_('NΓ‘zev Ε‘koly') )), required=True ) This is my view: class SchoolCreate(CreateView): model = School fields = ['name'] template_name = 'school_create.html' def get_context_data(self, **kwargs): data = super(SchoolCreate, self).get_context_data(**kwargs) if self.request.POST: data['school_formset'] = SchoolFormSet(self.request.POST) else: data['school_formset'] = SchoolFormSet() return data def form_valid(self, form): context = self.get_context_data() schools = context['school_formset'] print(schools) with transaction.commit_on_success(): form.instance.created_by = self.request.user form.instance.updated_by = self.request.user self.object = form.save() if schools.is_valid(): schools.instance = self.object schools.save() return super(SchoolCreate, self).form_valid(form) def form_invalid(self, form): print(form.errors) pass -
Streaming & downloading Large CSV files using StreamingHttpResponse
So the issue I am facing is trying to get our webservers export to CSV button working, one requirement is the file cannot be saved locally and must be streamed straight to the client. At the moment I am just trying to get a basic CSV file streamed and saved on the local machine from the server before I worry about rendering actual data. So, I have, on button click a post to my views where I wish to render then return a response. This was a $.ajax function but I have since changed it during testing and it now looks like this looks like: $("#exportbutton").click(function(e){ $.post("{% url 'doner:download' %}", function(data) { console.log(data); }); }) The code in the view looks like this (which happens to be a CTRL+V of an example from SO): def download(request): def stream(): buffer_ = io.StringIO() writer = csv.writer(buffer_) for row in rows: writer.writerow(row) buffer_.seek(0) data = buffer_.read() buffer_.seek(0) buffer_.truncate() yield data response = StreamingHttpResponse( stream(), content_type='text/csv' ) disposition = "attachment; filename=file.csv" response['Content-Disposition'] = disposition return response So after a lot of tinkering this is as far as I have got, it will 'stream'(?) the data back into the HTML page, the console.log will output β¦ -
Django REST Framework - PDF Generator
I created a new endpoint for an API (Django REST Framework) that generates a PDF from an HTML template. I follow the example from the plugin django-easy-pdf. It's working, but I would like to improve and to know what could be done in a better way. Asset is an object from the database with information. The idea is to print some rows on an HTML template to then convert to PDF. The HTML is fine, but I'm just not sure if I could improve on this view.

Django for/if in template
I have a simple question, but at the moment I'm to dumb to solve it. I have different lists passed from a view to a template to create data for a googletable. It's working quite well and looks like the following: var input_class = 'bc'; if(input_class == 'ab') { var rawData = [['ab'], {%for ab in ab_list%}['{{ab}}'], {% endfor %}]; } else if(input_class == 'bc') { var rawData = [['bc'], {%for bc in bc_list%}['{{bc}}'], {% endfor %}]; } else { var rawData = [['cd'], {%for cd in cd_List%}['{{cd}}'], {% endfor %}]; } For obvious reasons I want to put it in something like the following: {% for key, value in filter_lists.iteritems %} {% if input_class == '{{key}}' %} var rawData = [['{{key}}'], {% for item in value %}['{{item}}'], {% endfor %} ]; {% endif %} {% endfor %} Sadly it does not work. The keys are all strings like 'ab', the values are all the same lists as in the working example. Thanks for help, Jakob. EDIT: I'm using python 2.7, django 1.11 input_class is changed by a dropdown-menu which is created by a list. The same list is defining the keys of the dict. -
AngularJS and jQuery Datatables Integration
I'm using Django and there I'm serialising a query from my database. After I using GET Method get the JSON in AngularJS, I want to paint this in a datatable, and I am doing this using ng-repeat (I understand that ng-repeat works very slow), but only paint the data and nothing works anymore, when I try to search a data the table show empty. I found this angular-datatables web for can use jQuery Datatables and AngularJS, I tried to use the ajax option and the angular js option (there they also talk about the slowness of ng-repeat for the job), but I can not understand how to implement it in my code, I tried to look for code examples on the page but there is only about Angular (Angular2>) using typescript and in the explanatory code of the documentation it is not very clear to me if I should add ['datatables'] and related things even though the app contains other controllers that have nothing to do with datatables.

On the formatting of Python datetimes
A slight OCD question here - I'm using the {% humanize %} tag in Django which gives me date times returned in the following format: June 17, 2017 07:24 pm Now, within my post model in Django I am returning the following: def published_date(self): """Returns a humanized date format for Algolia indexing.""" humanized_published_date = str(self.publish.strftime("%B %d, %Y %I:%M%p")) return humanized_published_date All works well. HOWEVER, the format returned in the above method is: June 17, 2017 07:24PM I've had a previous read of the datetime documentation here (https://docs.python.org/2/library/datetime.html) specifically the section "8.1.7. strftime() and strptime() Behavior". I can see what I may need is the de_DE formatting - which displays a 12 hour clock suffix as pm and not PM. So, my question is this. How do I re-format date times to give a format as the following: June 17, 2017 07:24 pm.* (As mentioned in the above code - I'm currently using %B %d, %Y %I:%M%p). *N.B. I'm OCD to the point where I don't want June 17, 2017 07:24PM or even June 17, 2017 07:24pm! i.e., I need that space between the twelve hour clock and the ante meridiem and post meridiem suffixes. -

Whoosh haystack search error in django project
I am using Whoosh / Haystack in a Django project for text indexing and search. There is a search bar on the website. Results are refreshed and shown after every letter entered. I want to search the term 'income tax' through the search bar. When I start writing 'income tax', I get results till 'inc' (first three letters) and after that I get server error when I write 'o','m','e' and ' '. When I write 'ta' from 'tax', I get results shown again and after that again I get server error when I write 'x' of 'tax'. Also, when I search for the term 'income tax' using SearchQueryset in shell, I get a whoosh object containing more than hundred items. I can't understand this weird behaviour. -

Django - getting a path from a variable when saving models
My app has a simple process, the user uploads a gif file and then the gif is conveted to frames that are saved as objects. For the upload_to part of my gif, I run a function content_file_name() that uses uuid to create a folder path. I want the image frames to be saved to the same folder as the gif. Problem is, I can't set the path as a variable as much as I try. The variable needs to be defined first, but if I define it, it doesn't change no matter what I do. Here's what I got now: currentFilePath = '' # Defining the variable def content_file_name(instance, filename): ext = ''.join(filename.split())[:-4] foldername = "%s/%s" % (uuid.uuid4(), ext) store_random_path('/'.join(['documents', str(foldername)])) # Running a function to change the variable return '/'.join(['documents', str(foldername), filename]) def store_random_path(path): currentFilePath = str(path) # The variable should be changed here class Document(models.Model): docfile = models.ImageField(upload_to=content_file_name) def create_documentfiles(self): gif = Image.open(self.docfile.path) frames = [frame.copy() for frame in ImageSequence.Iterator(gif)] basename, _ext = os.path.splitext(self.docfile.name) for index, frame in enumerate(frames): buffer = BytesIO() frame.convert('RGB').save(fp=buffer, format='JPEG') destname = "{}{}.png".format(basename, index) finalImage = InMemoryUploadedFile(buffer, None, destname, 'image/jpeg', frame.tell, None) imageToSave = DocumentImage(imagefile=finalImage) imageToSave.save() class DocumentImage(models.Model): imagefile = models.ImageField(upload_to=currentFilePath) # Trying to β¦
