Re: Import csv file on django view

Hi Pandas require knows the encoding and delimiter previously when you use
pd.read_csv(filepath, encoding=" ", delimiter=" ") I think that is the same

Re: Import csv file on django view

[Ronaldo Mata]

Hi Kovy, this is not solved. Liu Zheng but using
chardet(request.FILES['file'].read()) return encoding "ascii" is not
correct, I've uploaded a file using utf-7 as encoding for example and the
result is wrog. and then I tried
request.FILES['file'].read().decode('ascii') and not work return bad data.
Example for @ string return "+AEA-" string.

Yes, the problem here is that the files will be loaded by the user, so I
don't know what delimiter I will receive. This is not a base command that I
am using, it is the logic that I want to incorporate in a view

Re: Import csv file on django view

[Ronaldo Mata]

Hi Liu thank for your answer.

This has been a headache, I am trying to read the file using
csv.DictReader initially i had an error trying to get the dict keys when
iterating by rows, and i thought it could be encoding (for this reason i
wanted to prepare the view to use the correct encoding). for that reason I
asked my question.

1) your first approach doesn't work, if i send utf-8 file, chardet returns
ascii as encoding. it seems request.FILES ['file']. read () returns a
binary with that encoding.

2) In the end I realized that the problem was the delimiter of the csv but
predicting it is another problem.

Anyway, it was a task that I had to do and that was my limitation. I think
there must be a library that does all this, uploading a csv file is common
practice in many web apps.

Import csv file on django view

[Ronaldo Mata]

How to deal with encoding when you try to read a csv file on view.

I have a view to upload csv file, in this view I read file and save each
row as new record.

My bug is when I try to upload a csv file with a differente encoding (not
UTF-8)

how to handle this on django (using request.FILES) I was researching and I
found chardet but I don't know how to pass it a request.FILES. I need help
please.

Re: Custom-DRF-Response

I Think that this should be a common approach, since many famous frontend
framework is easier to create logic to deal with that format response.

Re: Custom-DRF-Response

[Ronaldo Mata]

I think that this not depend of my serializer. I only want that the
response data will be inside data variable in the JSON response and i need
to add status variable and message to the JSON response. I can to rewrite
all Class Based Views of DRF to response with my desired format. but this
sound not very good.

I can do this:

def post(self, request, *args, **kwargs):
...blah...blah
...return Response({ 'status': true, 'message': 'login success',
'data': {'token':'345rjgjfegjgdsaj,fdgjsafgj'}})

right?

but this required rewrite all DRF methods on Class Based Views to change
the response format.

I'm trying to use Renderers. I think that is the best for this. But I'm not
sure how to pass message from views to renderers. it returns me to the same
problem.

But this required pass from every view message attribute to data (since all
messages depend on the view) example:

{ status: True, message:"user regitered", data: {user: {user detail,
token...}}} (Register View) --> has custom message
{ status: True, message:"logout successfully", data: {} (Logout View) -->
has custom message


from rest_framework import status
from rest_framework.renderers import JSONRenderer


class GlobalJSONRenderer(JSONRenderer):

def render(self, data, accepted_media_type=None, renderer_context=None):
"""
this function change the response format to return the follow
format:

{
'status': True o False, -> Depend of status code
'message': '', -> A message (not yet)
'data': {} -> All Data
}
"""
data = {
'status': False,
'message': '',
'data': data
}
response = renderer_context['response']
status_code = response.status_code

if status.is_success(status_code):
data['status'] = True

return super(GlobalJSONRenderer, self).render(
data,
accepted_media_type,
renderer_context
)

Thx for your answer. 

but this brings me to the second point. If I do that I must to rewrite all

I am basic in web development, but I would like to generate something like

When I select a make, the options for the model are automatically updated,
that is, when I select a make, the model input only shows the models
associated with that make.

Help me!

[Ronaldo Mata]

Hello! I would like you to help me implement a filter form, I put them in
cotexts:

Example:
I have a website about cars, I created my Car model with attributes such as:
- colour
- make
- model
- price

Now I want to find a way to make a filtering using a form, the case is that
the form will have three input type drop-down, [make, model, price], when
the user selects a make the model input must display only the models
available for that make, how to achieve that?

Is it necessary to implement a Make and Model model and associate them with
Car by a foreign key?

Re: about createsuperuser

[Ronaldo Mata]

Check your urls.py, is it admin registered?
