I have the form which i am showing by normal view. Then i am send the GET parameters to djnago ChangeList view like django does for lookups like this
student/?region__id__exact=1&status__exact=Published
now is there any way to remove that from the URL in the address bar.
I don't users to see what i am doing
The whole point of GET is that they are retrieved from the URL itself, removing them from the URL removes them entirely.
If you want them 'hidden' you will need to use POST.
The HTTP GET method of form submission passes the information from template to views through URL. If you want to "hide" information from URL use POST instead. In your form do like this:
<form action="/view_name/" method="post">
and in views:
request.POST['name']

I'm not sure if this is even possible, but I would like to grab a user's input, pull it into my views.py, manipulate it, and then use that data in other views.
I do not need this data stored in a database, as I won't be referencing it again, and I want to keep this as lightweight as possible.
Currently, I'm trying to pull data from espn's fantasy football site using the python library espnff. My homepage consists of a textfield box and a submit button (Think of google.com).
I have functions set up that will comb through an espn url such as http://games.espn.com/ffl/clubhouse?leagueId=123456 to grab the leagueID, from there I make use of espnff to grab more info on that league.
My ideal use case is someone comes to my site, copies and pastes their league url like the one above, clicks submit and then brings them to https://example.com/{{ leagueID}/ which will display different info that I gather.
I have not found a way to do this without submitting the user input to a model. Is possible to avoid using the database? If so how?
Not sure I understood it right, but what you are trying to do can easily be done without using any models/database or any other kind of persistent storage.
The user submits that information using the form, you grab the URL from the request object in your view, parse the URL to get the league_id and then redirect the user to /{league_id}.
Then on that view, you gather the league_id parameter (from the url), use the library (espnff) to fetch the data with that id and then render the template with that data.
For example, the implementation would be something in these lines:
Make a form in your html template:
<form method="post" action="/">
{% csrf_token %}
<input type="text" name="league_url"/>
<input type="submit" value="Submit" />
</form>
in urls.py:
url(r'^$', index_view, name="index"),
url(r'^(?P<league_id>[0-9]+)$', league_view, name="league_view")
in views.py:
def index_view(request):
if request.method == 'POST':
league_url = request.POST.get('league_url', None)
# Your code to parse the URL and extract the ID
return HttpResponseRedirect('/{}'.format(league_id))
else:
# render form template
def league_view(request, league_id):
# your code here using the league_id
# and render the page with data
(I didn't tested that code, I just wrote it quickly as an example of the flow)
The django documentation describes quite extensively how to do caching with django. You can find the documentation on how to set that up here
Once it's been set up you simply use the cache in the following way
from django.core.cache import cache
cache.set('my_key', 'my_value', 60) # number is in seconds
value = cache.get('my_key')
You can provide dictionaries and such as values. The caching framework will serialize that for you using pickle.
I have next task and dont know how to make it.
Web page shows to user list of objects. Every object has 2 button with urls like function_detail and function_change_history. First url need open the page about details of the object and the second url need to open the page about change history. I used get_absolute_url to make second url but dont know how to create first url cause I need to use get_absolute_url again.
models.py:
#reversion.register()
class Function(models.Model):
***FIELDS***
def get_absolute_url(self):
return reverse('project:function_change_history', args=[self.project_id, self.code])
urls.py:
url(r'^(?P<project_code>[0-9a-f-]+)/(?P<function_code>[0-9a-f-]+)/change_history/$',
function_change_history,
name='function_change_history'),
url(r'^(?P<project_code>[0-9a-f-]+)/(?P<function_code>[0-9a-f-]+)/detail/$',
function_detail,
name='function_detail'),
Is it possible to set 2 url in get_absolute_url?
Finally I found the decision. For function_detail I use get_absolute_url and for function_change_history I use in template {% url 'function_change_history' project_code=project.code function_code=function.code %}
I'm having issues with correctly sending and receiving a variable with a GET request. I cannot find any information online either. From the HTML form below, you can see I'm sending the value of 'question' but I'm also receiving 'topic' from a radio button in the form (though the code is for that is not below).
I want to send 'topic' using POST but use GET for 'question'. I'm aware that the form method is POST though I'm not sure how to cater for both POST and GET.
HTML Form:
<form method="POST" action="{{ url_for('topic', question=1) }}">
My second issue is that I'm unsure how to receive 'topic' AND 'question' from the form. I've managed to receive 'topic' as seen below but I'm not quite sure how to receive 'question'. Preferably it would be better for the URL to be like so:
www.website.com/topic/SomeTopic?question=1
For the code below, I found online that request.args[] is used for receiving GET requests though I'm not sure if it is correct.
Flask:
#app.route('/topic/<topic>', methods=['POST', 'GET'])
def questions(topic):
question = request.args['questions']
return render_template('page.html')
The question is
How do I send two variables from a form using GET and POST for different variables at the same time.
How would I go about receiving both variables?
The short answer to your question is that you can't send both GET and POST using the same form.
But if you want your url to look like you specified:
www.website.com/topic/SomeTopic?question=1
then you're almost there. First you will need to already know the name of the topic as you have to specify that in your call to url_for() for the questions url.
<form method="GET" action="{{ url_for('questions', topic_name="cars") }}">
# Your url will be generated as www.website.com/topic/cars
flask
# Note that I changed the variable name here so you can see how
# its related to what's passed into url_for
#app.route('/topic/<topic_name>')
def questions(topic_name):
question = request.args['question']
return render_template('page.html')
Now when you submit your form, your input will be sent as a GET, an asumming you have an input field with the name question you'll be able to get the value of that field.
Referring from the form topic of django documentation, if in a view function I write,
if form.is_valid():
return HttpResponseRedirect('/thanks/')
And in the form template I give the action like,
<form action="/your-name/" method="post">
Then on submit the form will go to the view mapped tho /your-name/ url in urls.py but what about the HttpResponseRedirect('/thanks/') line in the function from where I rendering the form? If a form is valid then I save the form. but what will be the url in the action of the form. now def get_name(request): is the function mapped to /user/ url. I hope you understand my confusion here. need some help.
This is an exemple of the "post redirect get" pattern - if a post is succesfull (the form was valid and the processing went ok), it's good practice to return a redirect, which will be followed by a get from the user-agent on the url you redirected to. It avoids multiple submissions if the user try to reload the page.
Where you redirect to is up to you - you can just redirect to the same view (usually displaying a success message to the user), or redirect to another view.
As a side note: hardcoding urls is a bad practice in Django, you should use the url reverse feature instead.
I am using django.contrib.auth and would like to redirect to the previous page after logging in. I would like something like the following: Django: Redirect to previous page after login except the redirected-to URL can contain a query string.
Currently I have the following link in my template:
Login
user_login is the name of my login view.
I would like to use {{ request.get_full_path }} instead of {{ request.path }} to get the current path including the query string, but this would create a url with a query string within a query string (e.g. /login/?next=/my/original/path/?with=other&fun=query&string=parameters) which doesn't work.
I also tried adding a redirect_to argument to my login view and passing the url with the query string as a arument to the url template tag. However this gives me a NoReverseMatch error.
How about escaping the get parameters and then unquoting them in the view?
html
Login
login view
if successful_login:
url_with_get = urllib2.unquote(request.GET.get('next'))
return http.HttpResponseRedirect(url_with_get)
PS: I've stumbled across your blog many times looking for PIP help : )
