Redirecting buttons with values to other django templates/views

Firstly, I am getting a csv file from the user.
(Template file:)
<form method="post" action="{% url 'rowcol' %}" enctype="multipart/form-data">
{% csrf_token %}
<input type="file" name="file" accept=".csv">
<button type="submit">Upload File</button>
</form>
Then i am generating a list of all the columns present in the file and then calling another html file. (views.py:)
def rowcol(request):
if request.method == 'POST':
file = request.FILES['file']
dataset=pd.read_csv(file)
lst=list(dataset)
return render(request, 'Link5_rc.html', {'arr':lst})
return HttpResponse('')
In that html file, i am creating buttons for all the columns present.(Link5_rc.html:)
{% for link in arr %}
<form action=" " method="post">
<button name="{{link}}" type="submit" value="{{link}}">{{link}}</button>
</form>
{% endfor %}
Now the following is the part where i am stuck: I want these buttons to redirect to another html page or maybe a view in views.py , where i can show to the user which column he/she selected and then perform further actions on that particular column.

You can pass one or more values to the request as in the following example:
Some text
You can use variables like:
Some text
In your app urls.py you should set the following to receive the extra data in the request:
url(r'^your_name/(?P<value_1>[\d\D]+)$', views.your_view, name="your_url_alias")
Then, in your view function you should receive the data as in:
def your_view(request, value_1):
An then you can use the value to filter the queryset.

How to read csv file in html?

I have a code and the thing I am not understanding is why a function of some_view in views.py is not fetching files from CSV. Is there something wrong? There is also html file by the name of index.html. I want it to fetch the first column of CSV and make a loop in html so that I don't have to repeat it every time.
views.py
def some_view(request):
reader = csv.DictReader(open('file.csv','r'))
csv_output = []
data = csv.reader(reader)
for row in data:
csv_output.append(row)
return render(request, 'index.html', context={'csv_content': csv_output})
index.html
{% for content in csv_content %}
<div class="row">
{% for k in content.items %}
<div class="column">
<p> value is {{v}} </p>
</div>
{% endfor %}
</div>
{%endfor%}

Django upload only csv file

I am trying to import csv file i am able to import without any problem but the present functionality accepts all file types, i want the functionality to accept only csv file. below is the view.py and template file.
myapp/views.py
def list(request):
# Handle file upload
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
importing_file(request.FILES['docfile'])
myapp/templates/myapp/index.html
<form action="{% url 'ml:list' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
<p><input type="submit" value="Upload"/></p>
</form>
EDIT
I could find a workaround by adding validate_file_extension as per the
django documentation
myapp/forms.py
def validate_file_extension(value):
if not value.name.endswith('.csv'):
raise forms.ValidationError("Only CSV file is accepted")
class DocumentForm(forms.Form):
docfile = forms.FileField(label='Select a file',validators=[validate_file_extension])

form widget to validate file extension
csv_file = forms.FileField(widget=forms.FileInput(attrs={'accept': ".csv"}))

added code snippet to the forms.py file to validate file extension and now it is working fine.
def validate_file_extension(value):
if not value.name.endswith('.csv'):
raise forms.ValidationError("Only CSV file is accepted")
class DocumentForm(forms.Form):
docfile = forms.FileField(label='Select a file',validators=[validate_file_extension])

Display form input with Django

So basically I want to make a simple form I can enter text and the after I hit submit, see the text.
Here is my forms.py:
class Search(forms.Form):
search = forms.CharField()
Here is my views.py:
def search(request):
context = RequestContext(request)
if request.method == 'POST':
search = Search(data=request.POST)
if search.is_valid():
ticker = search.save()
ticker.save()
success = True
else:
print search.errors
else:
search = Search()
return render_to_response('ui/search.html', {"search":search}, context)
Here is the html form that you use to type in (I'm using bootstrap for styling purposes):
<form class="navbar-form navbar-right" role="search" action="/search/" method="post" name="tick">
{% csrf_token %}
<div class="form-group">
<input type="text" class="form-control" placeholder="Enter stock symbol">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
And finally, I want the text entered in the form to be displayed on "search.html" which looks like this currently:
{% extends 'ui/base.html' %}
{% block title %} search {% endblock %}
{% block body_block %}
<br>
<p>test</p>
{{ form.search.data }} <!--I'm pretty sure this is not correct -->
{% endblock %}
Anyone know how I can do this? Thanks.

Your form name is search.
To render the value with modern django, you need to call the value method of the field, therefore your template should look like the following:
{{ search.search.value }}

Your template is wrong, as you suspect.
It is looking for a context variable named "form", but you have given it a context dictionary with a key named "search".
Also, "data" is the argument that you use to build up your Search object (correctly), but when you want to extract the user's input from it, you should use the field names instead, and you need to call value() on them in order to get the bound value. So, to get the contents of the text field called search, you should use search.search.value.
Try changing the line
{{ form.search.data }}
to
{{ search.search.value }}

Submitting multiple forms in Django

I'm not sure if i'm going about this completely the wrong way, but in my html template i have a for loop that i want to present multiple forms, and one submit button to submit the data from all forms:
{% for i in Attribute_list %}
<form action="/Project/create/" method=post>{% csrf_token %}
{{ i }}:
<input type=text name={{ i }}><br>
<hr>
{% endfor %}
<input type=submit>
The problem with this is it only submits the last form.
The other problem i'm running into is getting the data back from the view. Since i'm naming the form the variable "i", i don't know how to "get" this data in my views.py:
def create_config(request):
if request.method == 'POST':
data_list = []
for data in request.POST.getlist():
data_list.append(data)

can You check this?
<form action="/Project/create/" method="post">
{% csrf_token %}
{% for i in Attribute_list %}
{{ i }}: <input type="text" name="{{ i }}"><br>
<hr>
{% endfor %}
<input type="submit">
</form>
As I understand without JS regardless how many forms You create only one POST request will be made.
In oyur example HTML is not valid so It can behave different ways in different browsers. But as soon as You have not closed form last one should be submitted.
As for second part
def create_config(request):
if request.method == 'POST':
data_list = []
for data in request.POST.getlist():
data_list.append(data)
I think You should use your Attribute_list. Or You can just iterate over all `POST' variables obtained.
def create_config(request):
if request.method == 'POST':
data_list = []
for key in request.POST:
data_list.append(request.POST[key]) # or .extend(request.POST.getlist(key)
