I can't get this to work: I navigate to the page I want, but I'm doing something wrong with the variables it seems.
views.py:
#view_config(http_cache=1,route_name='hoofdpagina', renderer='templates/hoofdpagina.pt')
def hoofdpagina(request):
page = DBSession.query(MyModel) #.filter_by(id='1').all()
if 'form.submitted' in request.params:
name= request.params['name']
page2=Page(name)
DBSession.add(page2)
return HTTPFound(location=request.route_url('view_page',pagename=name))
return dict(page=page)
#view_config(route_name='diagnose', renderer='templates/diagnose.pt')
def diagnose(request):
return request
kak = ['test1','test2','test3t']
content = {"test1","test2","test3"}
return {'content' :content, 'test' :kak}
hoofdpagina.pt:
<form class="span12" action="/diagnose" method="POST">
<table class="table table-hover">
<thead class="header">
<tr>
<th>D Nr.</th>
<th>Datum</th>
<th>Patient</th>
<th>Prior</th>
</tr>
</thead>
<tr tal:repeat="Page page" >
<td tal:content="Page.dosiernummer"></td>
<td tal:content="Page.dosiernummer"></td>
<td tal:content="Page.datum"></td>
<td tal:content="Page.naamPatient"></td>
<td tal:content="Page.prioriteit"></td>
</tr>
</table>
</form>
<form action="/diagnose" method="post">
<input type="submit" value="Save" name="form.submitted" ></input>
<label name="name">et werkt slet</label>
</form>
I can show all the variables of page in my table. But when I press the submit button I can't get the content of the "name" label to my diagnose page. I don't know how I can show the value.
ps: question is based on this post: Pyramid app: How can I pass values into my request.route_url?
Instead of you'd need an input of some sort:
<input type="text" name="name" value="et werkt slet">
or type="hidden" if you don't want it displayed.
I'm still learning Pyramid as well, but I also wonder if from your code that the submit action is going to post to def hoofdpagina anyway. I think you might have to move your POST handling to:
#view_config(route_name='diagnose', renderer='templates/diagnose.pt')
def diagnose(request):
if 'form.submitted' in request.params:
name= request.params['name']
page2=Page(name)
DBSession.add(page2)
return HTTPFound(location=request.route_url('view_page',pagename=name))
a sollution is working with url dispatching like this:
_init_.py:
config.add_route('diagnose1', '/diagnose1/{dosierid}')
views.py
#view_config(route_name='diagnose1', renderer='templates/diagnose.pt')
def diagnose1(request):
tabeldata=''
dosierid = request.matchdict['dosierid']
now you have your id from one view to another.
In the init.py you have to add url dispatching (config.add_route).
Your can get the data out of the url and pass on to another page like this.

I have a form for a voting system. I have the candidates in a table row. At the end of the row I have button with the candidate ID
<form method="post">
<table>
...
<tr>
<td>name</td>
<td>campaign promises</td>
<td><button id="candidate_id"></td>
<tr>
...
</table>
</form>
"candidate_id" is an actual number and unique. I would like to get that id value from the post request, so I know which candidate was selected. Im hoping its as simple as
request.POST.Something
Yes, you can provide name attribute to the button, say for example candidate_id_value as:
<form method="POST">
<table>
...
<tr>
<td>name</td>
<td>campaign promises</td>
<td><button id="candidate_id" name="candidate_id_value" ></td>
<tr>
...
</table>
</form>
Then access this value in the view as:
request.POST.get("candidate_id_value",False)
I'd like to build a table with multiple items that have checkboxes, if those checkboxes are checked I want to update just those items via button click.
I already got an update view that does that, but only for one item and only if the save button for this item is pressed (every table item got it's own button). My code looks like this:
<table>
<thead>
<tr>
<th colspan="4">
<button type "submit">My Submit Button</button>
</th>
</tr>
<tr>
<th colspan="2">My Title</th>
<th>Movie title</th>
<th>Movie description</th>
<th>And so on</th>
</tr>
</thead>
<tbody>
<tr>
<th>
<input type="checkbox" class="custom-control-input">
</th>
<th>Data</th>
<th>Data</th>
<th>Data</th>
<th>Data</th>
<th>
<button>Button to edit this row item</button>
</th>
<th>
<button type="submit" form="movie{{ forloop.counter }}">Button to save the changes</button>
</th>
</tr>
<tr>
<th>
<input type="checkbox" class="custom-control-input">
</th>
<th>Data</th>
<th>Data</th>
<th>Data</th>
<th>Data</th>
<th>
<button>Button to edit this row item</button>
</th>
<th>
<button type="submit" form="movie{{ forloop.counter }}">Button to save the changes</button>
</th>
</tr>
</tbody>
<!-- the form for saving exactly one movie -->
<form class="hide" id="movie{{ forloop.counter }}" action="{% url 'myapp:movieDataUpdate' pk=movie.pk %}" method="post">
{% csrf_token %}
</form>
</table>
This is my existing view/urls/form for the Save Button on each row:
urls.py
from django.conf.urls import url
from . import views
app_name = "myapp"
urlpatterns = [
url(r'^$', views.AllMovies.as_view(), name="index"), views.UpdateMovieDataView.as_view(), name='movieDataUpdate'),
]
views.py
class UpdateMovieDataView(UpdateView):
model = Movie
form_class = UpdateMovieDataForm
success_url = reverse_lazy('myapp:index')
def form_valid(self, form):
self.object.slug = slugify(form.cleaned_data['title'])
return super(UpdateMovieDataView, self).form_valid(form)
forms.py
class UpdateMovieDataForm(forms.ModelForm):
class Meta:
model = Movie
fields = ['title', 'date', 'director', 'runtime', 'genre', 'status']
I hope someone could help me here, tried to figure it out, but didn't succeeded yet. Maybe someone with a lot more experience can help :)
You can add javascript on it (jQuery is easy to start).
You first add jQuery to your html page (download here).
Then you add an id to your checkbox (example below):
<input id="my_checkbox1" type="checkbox" class="custom-control-input">
And then, add a javascript code (at html) that detect the checkbox change, and make an AJAX to your server.
<script>
$("#my_checkbox1").change(function() {
if(this.checked) {
$.post("{% url 'myapp:movieDataUpdate' pk=movie.pk %}", {},
function(data, status){
console.log("Data: " + data + "\nStatus: " + status);
});
}
# If you want, make an else
});
</script>

I encounter some difficulties to log on a website from a python script, in order to retrieve data from it later on, once I will be connected.
I think that the part of the HTML page with the form expecting username and password is the following :
<div class="contentLogin">
<form action="/login/loginSubmit" method="post" class="memberLogin">
<table cellpadding="0" cellspacing="0" border="0" >
<tr>
<td><label class="color2">Déjà membre</label></td>
<td> </td>
<td><input type="text" value="pseudo" class="input" name="login" id="login" /></td>
<td><input type="password" value="pass" class="input" name="pass" id="pass" /></td>
<td><input type="submit" value="ok" class="color2 loginSubmit" /></td>
</tr>
<tr>
<td colspan="3"></td>
<td colspan="2" >
Mot de passe oublié ?
</td>
</tr>
</table>
</form> </div>
I would like to use the "requests" module of python langage, to do the POST request that will connect me to the site.
My code already contains the following commands :
import requests
pars = {'login': 'dva2tlse', 'pass': 'VeryStrong', 'action': 'Idunno'}
resp = requests.post("http://www.example.com", params=pars)
But it seems not to work, because I even do not know WHICH action should be indicated within th POST request. (I do not even know how exactly to use it, since I never done it)
Thank' you to help me make all that work correctly,
David
Change the url value in requests.post to match the one given in <form action> attribute.
Also, remove the action key in your pars dictionary.
pars = { 'login': 'dva2tlse', 'pass': 'VeryStrong' }
resp = requests.post("http://example.com/login/loginSubmit", params=pars)
If you want to keep your login state for further page calls, you can use requests.Session()
s = requests.Session()
pars = { 'login': 'dva2tlse', 'pass': 'VeryStrong' }
resp = s.post("http://example.com/login/loginSubmit", params=pars)
As long as you keep using s, you will stay logged in.
I am new to Python, GAE and the datastore model. So there are lots of things which I do not know yet, so please be patient :)
I am working on a web service that allows people to post 'name' and 'desc' (description) of an item and it will be included in a table on the same page. However when I clicked the submit button I got the error: 404 Not Found, The resource could not be found.
I am expecting a lot of things to be wrong in my code shown below (I only include short snippets of my code which I think is relevant to make it easier for reading), and my biggest problem is I have no idea which parts are wrong or which specific questions to ask. But I hope I can use this chance to learn more about everything that's involved in my code (Jinja, HTML, GQL etc), and how I can fit them all together.
class Events(ndb.Model):
name = ndb.StringProperty()
desc = ndb.StringProperty()
class Promote(webapp2.RequestHandler):
def get(self):
query = ndb.gql("SELECT * "
"FROM Events "
)
template_values = {"events" : query,}
template = jinja_environment.get_template('promote.htm')
self.response.out.write(template.render(template_values))
def post(self):
event = Events(name = self.request.get('name'), desc = self.request.get('desc'))
event.put()
self.redirect('/promote')
app = webapp2.WSGIApplication([('/', Main),
('/publicsearch', PublicSearch),
('/promote', Promote)],
debug=True)
This is my html code for that page.
<div class="jumbotron">
<div class = "container">
<form action="/promote" method="post">
<fieldset>
<div class="row-fluid">
<p> Promote your event here! </p>
<div class="row-fluid">
<div class="span6">
<p> Name of event: <br>
<textarea class="input-block-level" name="name" rows="1" cols = "50"> </textarea></p>
<p> Event description: <br>
<textarea class="input-block-level" name="desc" rows="3" cols = "50"> </textarea></p>
<p><input type="submit" value="Submit">
</div>
</div>
</div>
</div>
</div>
<h4> Events feed </h4>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th width="30%">Name</th>
<th>Description</th>
</tr>
</thead>
<tbody>
{% for event in events %}
<tr>
<td>{{ event.name }} </td>
<td>{{ event.desc }} </td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
Your form is trying to post to a handler with a url of /wishlist however the only handler for POST methods you have registered is for /promote.
These things need to match up. Either change the form or the handler mapping.
Also while you are at it check that your app.yaml makes sense. Have a look in the logs whilst you are at it, you will see what URL is being requested.
I have multiple forms on one page and my view is handling these by checking the value of the submit. This seems to work all fine, however on of my forms is getting the error below.
'QueryDict' object has no attribute 'method'
VIEW
def all(request):
if request.method == 'POST':
if 'all' in request.POST['submit']:
all(request.POST)
elif 'addtype' in request.POST['submit']:
addtype(request.POST)
elif 'addnewpm' in request.POST['submit']:
addnewpm(request.POST)
elif 'addnewspec' in request.POST['submit']:
addnewspec(request.POST)
elif 'update' in request.POST['submit']:
update(request.POST)
elif 'addnewrecord' in request.POST['submit']:
addnewrecord(request.POST)
Basically I am just passing the post values to seperate functions based on which submit button was pressed. They all work fine except for the first one 'all'. The 'all' submit button is submitting a large amount of data, and I can see all this data in the traceback.
Maybe it has something to do with my HTML code.
<table class="gridtable">
<tr>
<td class="topheader-left" colspan="10">
<form action="" method="post">
<button type="submit" value="all" name="submit" style="border:0px;">
<img src="{% get_static_prefix %}images/update.png" style="width:27px;height:27px;">
</button>
</td>
</tr>
Below this I just have a large number of table cells with fields and a /form at the end.
The code from one of the forms on my page that works fine.
<table width="100%">
<tr>
<form method="post" action="">
<td>
<input id="newtype" type="text" name='newtype' size="40" value="Service Type">
</td>
<td>
<button name="submit" type="submit" value="addtype" style="border:0px;">
<img src="{% get_static_prefix %}images/Add-icon.png" width="20" height="20" border="0">
</button>
</td>
</form>
This form seems to work fine. I don't understand what I am doing differently.
Cheers guys.
Seems like a simple function name collision. Your view method name is all and you're calling all(request) again and again, and again :) if the value of submit == all.
Using in to look for the value of submit in request.POST seems odd. Why not just set the value once and compare it that way?
submit = request.POST['submit']
if submit == 'all':
# call method
elif submit == 'addtype':
# etc
