[web2py] Re: json empty with jquery
First of all thanks so much for your help, Leonel. I finally got it.
I had a concept mistake. I had to declare a variable to get the data of the
client wiht the same structure of the data. I used datos =
str(request.vars), it is correct because I can retrieve data: {'key':'value
','key2':'value2'} as a string, but it is not the proper way. The proper
way is
datos = str(request.vars.key),str(request.vars.key2)]
So I can get the values at the client with
data.datos[0], data.datos[1]
That is solved. The second issue I had was tha I wanted to send the values
to the controller, to store them in a database. I finally use the jquery
set val () and send it through a form field.
$(#test).val(data.datos[0])
That's it.

Do you want to change the HTML after getting the response? If it's that
you can do something like this:
{{extend 'layout.html'}}
h2Template default/test2.html/h2
dl
dtKey/dt
dd id=key/dd
dtKey2/dt
dd id=key2/dd
/dl
script
$(document).ready(function(){
$.ajax({
type: 'POST',
url:'http://127.0.0.1:8000/MFREG/default/test2.json',
contentType: application/json; charset=utf-8,
data: {'key':'value','key2':'value2'},
dataType: 'json',
success: function(data){
for (var key in data) {
$('#' + key).text = data[key];
}
}
});
});
/script

[web2py] Re: json empty with jquery
Sorry, but they are not stored in request.vars as expected. It works fine
in the alert window, but I can't retrieve the values in the controller to
handle them. I have tried with a diferent function in the controler, like
this:
def test2():
result=testpost()
return locals()
def testpost():
datos=str(request.vars)
key=request.vars.key
return locals()
The view:
{{extend 'layout.html'}}
h2Template default/test2.html/h2
{{=BEAUTIFY(response._vars)}}
script
$(document).ready(function(){
$.ajax({
type: 'POST',
url:'{{=URL('default','testpost.json',args='datos')}}',
data: {'key':'value','key2':'value2'},
dataType: 'json',
success: function(data){ alert(Data:+ data.datos); }
});
});
/script
And the result:
https://lh5.googleusercontent.com/-PIXsDgJWotI/VJFcBhXJLTI/ArI/YBS5zRL7dvA/s1600/Selecci%C3%B3n_808.png
Maybe I have to declare key and key2 as var in the script? Because the
values I get in the request.vars are Storage{} instead
of {'key':'value','key2':'value2'} as desired. So they are not stored in
request.vars

[web2py] Re: json empty with jquery
Jacinto they are in request.vars otherwise you wouldn't see them in the alert window. Let's walk through what is going on here: 1. You open the address in the browser http://127.0.0.1:8000/MFREG/test2 as the extension is omitted web2py assumes HTML and your HTML view is processed 2. That URL doesn't have any vars so the HTML made by BEAUTIFY response._vars shows them empty 3. When the document is ready your browser makes an ajax request that does have vars. 4. The server answers in json because you used the .json extension and you get the result in the success function in its data argument, you then show it in an alert. As you can see the HTML is never changed after your initial request - that didn't have vars - hence why it keeps showing you exactly that. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

Yes, so what do you suggest?. Do I have to fill my request.vars before the document is loaded? How can I do it?

[web2py] Re: json empty with jquery
I mean, I try to send data: {'key':'value','key2':'value2'}
so I expect to get {'key':'value','key2':'value2'}
in the controller.
I've tried your suggestion and that's the result:
https://lh5.googleusercontent.com/-HUzPxb4Z-ik/VJBcmcKfUqI/Aqo/aOUHGUqv_FY/s1600/Selecci%C3%B3n_805.png
I get the same that in the datos var, in the controller. But, the Storage{}
list is empty.

[web2py] Re: json empty with jquery
Well it's supposed to be empty. You're calling the controller like this: http://127.0.0.1:8000/MFREG/default/test2.json This URL has neither args nor vars. Then you do this: datos = str(request.vars) datos2= request.args(0) request.vars is an empty Storage so when you convert it to string you get Storage(), datos2 is None because there is no request.args(0) -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: json empty with jquery
Ok, I.m getting closer. So I change my url call, like this
url:'{{=URL('default','test2.json',args='data.datos')}}',
but I still have an empty reques.vars. How should I call the controller to
pass the data field as a json from the view scritp to the controller?
What I am looking for is to send the position.coords.latitude or vars like
these from the browser to a controler in server.

Humm request.vars shouldn't be empty because you're sending them in data. Add a print request.vars to the controller and see what's there. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: json empty with jquery
I did with
{{=BEAUTIFY(response._vars)}}
and the result is:
datos:Storage {}
So request.vars is empty.
If I change the post method for a get method, I can see the correct result
at the alert window, but not in the controller, I mean it works in the
client side:
Wiht get method:
https://lh5.googleusercontent.com/-_9jLacZBDWM/VJBw0zK5TRI/Aq4/KN46UfH72LU/s1600/Selecci%C3%B3n_806.png
The alert window is ok but the datos var an empty storage objetc.

Well
{{=BEAUTIFY(response._vars)}}
Won't see anything because the vars are only there in the ajax request.
That's why it works in your alert. It should work with POST too.
