Pass parameters with tilde in URL in django rest framework | python

  • 772

I am using django rest framework to generate a file, I have this function in my views.py:

def InformacionBibTex(request, bloque, idUsuario):
   print('BLOQUE', bloque)

   #...
   return response

I use this function to use it in my urls.py:

urlpatterns = [
  path('informacion_bibtex/<slug:bloque>/<int:idUsuario>', views.InformacionBibTex),
]

slug:bloqueIn this url I pass a and a as parameters int:idUsuarioto be able to use them in my function.

I pass the parameters from my frontend service in Angular through a request Get:

generaInformacionBibTex(bloque, id_user){
    const httpOptions = {
      responseType: 'blob' as 'json',
    };
    return this.http.get(this.url + 'informacion_bibtex/' + bloque + '/' + id_user, httpOptions);
  }

The URL that I send to my server is this:

http://localhost:8000/api/informacion_bibtex/ARTÍCULOS/127

The problem I have is that when making the request to the server it gives me the following error

"GET /api/informacion_bibtex/ART%C3%8DCULOS/127 HTTP/1.1" 404 11500

This due to the tilde that it has ARTÍCULOS, the server puts various characters such as percentages and numbers.

The same thing happens with spaces:

"GET /api/informacion_bibtex/GRADO%20ACAD%C3%89MICO/127 HTTP/1.1" 404 11520

In this case what I send is:

http://localhost:8000/api/informacion_bibtex/GRADO ACADÉMICO/127

How can I make the server accept the request Getthat I make from my frontend with parameters that contain accents and spaces. I hope you can help me. Thank you!

    The URL dispatcher is expecting a slug but is not receiving it. A slug only allows ascii letters, numbers, hyphens and underscores, anything else will not fall under that rule.

    You can change the URL definition to receive strings with:

    urlpatterns = [
  path('informacion_bibtex/<str:bloque>/<int:idUsuario>', views.InformacionBibTex),
]

    Or, if you want to use slugs and are expecting to access a model by name, use slugify to override the model save.
