Re: [web2py] Re: links in texts stoded in a database
I tried ckeditor and I've got an editor in admin so I can insert links, so
far so good.
but the text is still rendered plain with html tags visible.
my function and db in db.py: (text field is the field I want to insert
links into)
def advanced_editor(field,text):
return TEXTAREA(_id = str(text).replace('.','_'), _name=field.text,
_class='text ckeditor', value=text , _cols=80)
db.define_table('blog',
Field('date','datetime',default=request.now),
Field('image','upload'),
Field('imageTitle','text',default="image text"),
Field('title','text',default='imager text here...'),
Field('text','text',default='blog text
here...',widget=advanced_editor),
Field('votes','integer',default=0),
Field('plus','integer',default=0),
Field('minus','integer',default=0))
#format = '%(title)s')

Re: [web2py] Re: links in texts stoded in a database
just to clarify, my problem is that html tags in my input text area is just
rendered as tags, naturally because the field is classified as text and
nothing else. I need to render the html elements when displaying text.

Re: [web2py] Re: links in texts stoded in a database
the XML function solved the problem:

thanks.

Re: [web2py] calling custom javascript functions
I just wanted to see if it's possible to call custom made js functions
using jQuery. I found that it is possible to call by using this function:
$(document).ready(function() {
$(function_call());
}
css tags can also be added.
but it is simpler to just use myfunction();
In the web2py book all examples covers jQery effects but I couldn't find
any information about calling custom made js functions.

Re: [web2py] Re: controller not returning java script variable correctly
ok, now I undestand what you mean:
def test():
print "called2"
data3=[3, 6, 2, 7, 5, 2, 0, 3, 8, 9, 2, 5, 9, 3, 6, 3, 6, 2, 7, 5, 2,
1, 3, 8, 9, 2, 5, 9, 2, 7]
return 'graph1(%s);' % data3
ajax('{{=URL('test')}}',[],':eval');
graph1 is the actual function, the write function was just for testing.
This works but it means that I have to make a python function for every js
function call when passing values from python functions.

[web2py] difference between crud.select(db.hem,query) and db(query).select()?
hi When doing results=crud.select(db.hem,query) I got a list containing the result with html tags in the beginning and the end. But I am not able to access different fields like result.info and so on. When I am using results=db(query).select() I can do results.info. Is there any way to get individual fields using crud.select(db.hem,query)? --

Re: [web2py] Re: controller that don't returns a view?
Thanks. Actually the call comes from a button: It has to provide the right result.id so the like addition relates to the right post. I will try using callbacks from the button call to see if it works. On Thu, Dec 6, 2012 at 11:17 PM, Niphlod wrote: > Learned something also today!

Re: [web2py] Re: calling LOAD from a button
thanks
I use the following solution;
{{for result in res:}}
{{=result.id}}
{{=result.title}}
{{=A(TAG.i(_class="icon-plus-sign"), _rel="tooltip", _title="testing",
_class="btn", _href='#', _onclick="jQuery('#uc').toggle();")}}
{{=LOAD('default','comment.load',args=result.id,ajax=True)}}
with this I can load the form.
two things remains.
1. I need to close or clear the form so that it is clear that it has
been submitted.
2: I need an unique id for every comment, something like this:
{{a=0}}
{{for comment in com:}}
{{if comment.post_id==result.id:}}
{{a=1}}
{{=comment.created_on}}
{{=comment.created_by}}
{{=comment.comment}}
{{pass}}
{{pass}}
is it possible to create unique id in any other way? the above
solution to add result.id to the id works for displaying comments but
not for displaying forms.

Re: [web2py] Re: custom form validation
ok. another thing is that if I use a regular form, {{=form}}, then
validation works but not if I use the custom form. Also form.process()
works, so the problem seems to be related to custom forms.

Re: [web2py] Re: custom form validation doesn't work
here is the custom form:
{{=form.custom.begin}}
date: {{=form.custom.widget.created_on}}
name: {{=form.custom.widget.created_by}}
mail: {{=form.custom.widget.mail}}
link: {{=form.custom.widget.link}}
comment:{{=form.custom.widget.comment}}
{{=form.custom.submit}}
{{=form.custom.end}}
The second question is as follows: when the form is filled and
submitted, it should be clean, i.e no text in it or something else
that indicates that the submission was successful and possible
collapsed to. It is true that the redirect(index) returns data from
the data base but I want to avoid that in this case, so another form
of redirect would be better.

Re: [web2py] Re: controller not returning variables
ok, to include everything in the for loop is more elegant. The reason
why I wanted to separate the call to sidebar.py is that the sidebar
contains almost static material that doesn't change that much, while
the main page (index page) has content that changes more. In the first
version I had the db variable defined in the index.py controller. I
Think this is a common situation, sidebar content that doesn't change
much and a main part that is updated more frequently so some sort of
content separation is preferable.
The solution to put it in the view instead is ok for me.

Re: [web2py] Re: anyone tried jQuery svg?
Thanks for the replies. d3js looks very interesting, I will look into that.
