Passing form input data to post request

I'm very new to Python/Django and trying to create search box which grabs the data from an API and returns the result on HTML. Just like any other search engine does.

I have to passed the token via headers. This is my current code.

url.py

    urlpatterns = [
        url(r'^admin/', admin.site.urls),
        url(r'^$',views.search, name='search'),]

form.py

from django import forms

class SearchForm(forms.form):
search_company = forms.CharField(label='search_company',max_length=100)

views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect
from django import SearchForm

def get_search (request):
    if request.method == 'POST':
        form = SearchForm(request.POST)

        if form.is_valid():
            return HttpResponseRedirect('/search.html')
        else:
            form = SearchForm()

        return render(request, "main/search.html")

search.html

  <form class="col-md-6" action="/search.html/" method="post">
      {% csrf_token %}
      <label for="search_company">Search Company</label>
      <input type="text" name="search_company">
      <input type="submit" value="ok">
  </form>

this is my error in console

The SearchForm is in your django app and not in your django library.

Use from .form import SearchForm

Also, move your else to ( if request.method == POST ), so that the form is sent if method is not post.

And I would suggest you to use reverse() function to resolve url ,

HttpResponseRedirect(reverse('search'))

from django import SearchForm
ImportError: cannot import name 'SearchForm'

The updated error is because you are trying to import the SearchFrom from the root of the django library.

You need to import your SearchForm from your app, so in your views.py

from django import SearchForm

should be something like 

from myapp.form import SearchForm

Also, in Django it is common to call your forms containing file forms(plural) instead of form (singular), since it can contain multiple forms.
