Re: [web2py] Re: Upload form
Thank you fpr these details.

The admin upload widget you see is actually handled via JS in layout.html:
https://github.com/web2py/web2py/blob/master/applications/admin/views/layout.html#L80
There is some associated CSS in bootstrap_essentials.css:

Again:

If I want to upload a package in the admin app it looks like upload2.png

[web2py] how do i return several rows from json using ajax?
hi,
i have a function in a controller which queries the database if the user is
logged in and then grabs the information using json (as below)
def pruchaseHistoryJson():
if auth.user:
rows = db(db.sale.auth_id == auth.user.id
).select(db.sale.title,
db.sale.price,
db.sale.shipping_address,
db.sale.shipping_state,
db.sale.shipping_city,
db.sale.shipping_zip_code)
else:
redirect(URL('default', 'user/login'))
import gluon.contrib.simplejson as json
prodHistory = json.dumps([{'name': i.title,
'prodValue':i.price,
'shipAdd':i.shipping_address,
'shipCity':i.shipping_city,
'shipState':i.shipping_state,
'shipCode':i.shipping_zip_code} for i in
rows])
return prodHistory
i am now trying to figure out the $.ajax function so i can display this
result in a view. below is the $.ajax function. i get an error using
firebug stating, invalid request. What do i do to fix this?
script type=text/javascript
function testAjax()
{
$.ajax({
type: 'GET',
url:'127.0.0.1:8000/suzannecollins/onlineStore/pruchaseHistoryJson',
data:{prodName: rows.name, prodCost: rows.prodValue, prodAdd:

success: function(msg){
prodHistory = $.parseJSON(msg);
$(#shopProdHistory).html(prodHistory.prodName

[web2py] Re: how do i return several rows from json using ajax?
I have made changes to the $.ajax which now gives me a different error but
i think it's moving forward.. i have changed this line..
url:{{=URL('suzannecollinshttp://127.0.0.1:8000/suzannecollins/onlineStore/pruchaseHistoryJson',
'onlineStore', 'purchaseHistoryJson')}},
the error i encounter now is.. SyntaxError: JSON.parse: unexpected character
according to firebug, it's actually getting all the data and i can see that
all the data is in response tab of the firebug debugger.. but not sure what
the above error means..

[web2py] How to use response.flash() to inform user about current status of a process
Hello, I try to use response.flash() to inform my users whats happening on my website. Is there a way to quick update the displayed message? Example: User clicks on a button, response.flash() informs about the start of a process. The user waits, response.flash() informs about several process steps and after the process has finished, the response.flash() informs about the result of the process.

[web2py] Re: how show images from side sites?
{{ = XML('img src=%s' % 'https://some_url/image01.jpg') ) }}
The above code is fine, except there is an extra ) at the end. Another
option is to use the IMG helper:
{{=IMG(_src='https://some_url/image01.jpg')}}
https://money.yandex.ru/i/shop/mosenergosbut.gif
If you are wondering why the above image in particular doesn't show up when
you attempt to display it with an img tag, they are probably using some
mechanism to prevent
hotlinkinghttp://simple.wikipedia.org/wiki/Hotlinking(e.g., they check the
HTTP_REFERER header and return a 302 not found error
when external sites attempt to load the image). If you want to display the
image (and doing so is not prohibited by copyright), you will have to
download the image and serve it yourself.

[web2py] Re: How to use response.flash() to inform user about current status of a process
response.flash is used to set a fixed content into the layout.html This happens to be a div class=flash/div in the scaffolding app. That being said, you can't update the contents without refreshing the page, and / or using ajax. The implementation relies entirely on how your app works (i.e. how the page fetches the progress of the process steps). web2py.js has a js function to update the contents of the flash message and to display it (because usually it's hidden). try $.web2py.flash(message, status) it will insert message into the flash and add status classes to the corresponding div.

[web2py] Access to server variables from within javascript
How can I access the web2py object passed to the view with Javascript.
For example, I am trying to use jquery to retrieve some additional data for
the current record being edited.
When i try and invoke the jquery call passing the id of the edited record,
i.e. results.update_form.custom.dspval.id I am unable to reference it in
javascript, but can using the templaye language (i.e. {{print
results.update_form.custom.dspval.id}}.
Here is the jquery call:
$().ready(function(){
console.log('--- all is loaded ' + Date());
console.log('+++');
if (results.update_form.custom.dspval.id != null){
jQuery.getJSON({{=URL(get_days,args=[results.update_form.custom.dspval.id])}},
function(msg){
console.log('got some data')
console.log(msg);
})
}
I am useing firebug and tried to inspect the dom to find but am unable to
do so.
Any help would be appreciated as I bang my head against the wall trying to
figure out this front end development.

[web2py] Re: Access to server variables from within javascript
It's kind of the foundation of any template language to have some sort of
delimiter to import variables and such : anything you need to use in the
view coming from something that was on the controller MUST be called with
{{=something}}.

[web2py] Re: Access to server variables from within javascript
Niphlod thanks for the quick reply.
I was heading down that path.
I added the following in the viewcode
{{res=results}}
with the hopes of being able to reference res form javascript. But have
not figured it out just yet. Is this the common way to get access to the
server/template info form within javascript?

[web2py] Anchor callback option and form submit
Good evening,
I've just discovered the possibility to use in the view of the callback
option when we want to create a link, e.g. {{=A('mypage',
callback(URL='myfunction'), target='myID'). I found it really useful for
not loading a new page again. The problem is that the callback calls a
function that return a simple form that is correctly shown inside that div
but when i press the 'submit' button... the page refresh, but nothing
happen on the db. Basically nothing is register.
What am I doing wrong? I am not really interested in fixing this specific
problem rather to understand how it works and what I didn't get.
Regards,
Riccardo
P.S. I attach the code if it might help:
def addPet():
db.pet.owner_id.readable = False
db.pet.owner_id.writable = False
db.pet.owner_id.default = auth.user.id
form = crud.create(db.pet, onaccept=lambda form: testAnotherFunction(
form.vars.id), next=URL('welcome'), message='The pet has been added')
return dict(form = form)
IN THE VIEW WELCOME.HTML
...
li{{=A('Add a Pet', callback=URL('addPet'), target=MainContent )}} /li
...
div id=MainContent
Replace the content
/div
ADDAPET.HTML
div class=row
div class=span5 offset1id=addPetForm
{{=form}}
/div
/div

[web2py] Re: Access to server variables from within javascript
You can use the web2py template syntax within your JS code, just as within
HTML:
if ({{=results.update_form.custom.dspval.id}} != null){
Above we have the web2py template delimiters, {{...}}, within the JS code.

[web2py] Re: Anchor callback option and form submit
the callback argument is not meant to load a fragment and keep it like a
component (meaning, trapping all links, form submissions, redirections etc.
in that fragment).
callback was meant instead to either click on a button and show the result
in a fragment (i.e. action completed) and/or click a button to remove an
element from the page (i.e. remove a line from a table).
For a component-like behaviour, please use
A('mypage', _href=URL('myfunction'), cid='myID')
or the equivalent
A('mypage', _href=URL('myfunction'), target='myID')

Re: [web2py] Re: Documentation of the date time picker from dynarch, version 1.0
Thank you - this will help!
By the way: is there any full description for this program?
2013/11/3 Paolo Caruccio paolo.carucci...@gmail.com
In order to translate the text in the calendar you could adapt the
attached calendar-en.js.As an example you will find here also attached
calendar-it.js (italian translation)
Put the translation file in application/static/js folder.
In layout.html after (I would suggest just before /body tag)
{{include 'web2py_ajax.html'}}
write
script src={{=URL('static','js/calendar-it.js')}}/script
of course you have to replace calendar-it.js with the name of your
translation file.
If you would like apply the translation file according to browser language
you could write in layout.html :
{{calang = T.accepted_language or 'en'
response.files.append(URL('static','js/calendar-%s.js' % calang))
}}
just before
{{include 'web2py_ajax.html'}}
In this case if the translation file doesn't exist then will be applied
the english translation.
Anyway, calendar-en.js is not necessary because calendar.js contains
already the english terms.

[web2py] upgraded to 2.7.4 no admin ui
Upgraded to 2.7.4 (from 2.5.3 I think...) two different ways: 1) used the upgrade in place feature (yes, experimental but it has worked several times before--thank you for that!). The apps ran but I could not get into admin. I could do some of appadmin--database views, but design would not work. Later, appadmin also stopped working. NEWINSTALL was never replaced. The error is not very informative: Internal errorTicket issued: admin/98.247.169.56.2013-11-04.06-14-45.aaa6fb9b-c14e-443e-afc4-cf32bef55e3bhttps://www.lewcl.com/admin/default/ticket/admin/98.247.169.56.2013-11-04.06-14-45.aaa6fb9b-c14e-443e-afc4-cf32bef55e3b Clicking on the ticket just generates another ticket (of course, because the tickets are shown in the admin interface...). 2. I upgraded a second time by creating a clean web2py install from sources and then copied over key files and directories from the old version (now, unfortunately altered by the upgrade in place): 2 of my applications--entire directories routes.py parameters_443.py scgihandler.py (wonder if I got an old version of this file--would it matter?) __init__.py (it's empty--really just need the file name there for python to load web2py) There is no wsgihandler.pyc file in the web2py directory for this version, suggesting it's never been run--I thought that wsgihandler.py is what uwsgi uses to start the python process... This second approach doesn't work at all. Obtain the dreaded: uWSGI ErrorPython application not found I never touched the nginx or uwsgi configs. I have really totally forgotten how. I hope I never have to do it again. It's just such a mess of inter-related config files in different syntaxes scattered all over the file system. The way I switch back and forth between the 2 configs of web2py is by renaming the web2py directory. I stop nginx and uwsgi. Then start uwsgi and nginx (in that order). It's hard to say that the directory renaming hack causes the problem. The upgrade-in-place version always runs (after the stop and start); but the 2nd config never runs. It seems like a crucial file is missing from default file structure of 2.7.4--which is there when upgrading in place, but not with a clean install. I just can't figure out what the critical file is. --- As usual, I am stumped by config. I wish someone would write a python, not bash, script that fully installed web2py and all of its dependencies in the optimal way. There are a lot of variations that don't seem to produce benefits. Really important functional differences (as opposed to style such as whether configuring uwsgi with ini, xml, or other files) could be part of a SMALL list of parameters. Happy to provide any samples of config files if you can point me to where they are. - Lewis -- 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: upgraded to 2.7.4 no admin ui
Found the reference to the 2.61 changes. I copied appadmin from welcome to
my two applications, likewise web2py.js (into static/js). I copied
wsgihandler.py from the handlers directory.
This did not fix anything. And really didn't do anything as I started from
a fresh install from sources.
No, there is something that the uwsgi config just doesn't track--something
is missing from the new web2py file structure that must be hardcoded in the
classic uwsgi config.
There are so many approaches to configuring uwsgi that can be used
concurrently, which are scattered into multiple locations, that I cannot
tell what actually governs what happens. This is the web2py.xml file but I
have no idea if this is really doing anything:
uwsgi
pluginpython/plugin
socket/run/uwsgi/app/web2py/web2py.socket/socket
pythonpath/var/web2py//pythonpath
app mountpoint=/
scriptwsgihandler/script
/app
master/
processes4/processes
harakiri60/harakiri
reload-mercy8/reload-mercy
cpu-affinity1/cpu-affinity
stats/tmp/stats.socket/stats
max-requests2000/max-requests
limit-as512/limit-as
reload-on-as256/reload-on-as
reload-on-rss192/reload-on-rss
no-orphans/
vacuum/
/uwsgi
This might be the governing nginx config for the web2py server:
server {
listen 80;
server_name $hostname;
location ~* /(\w+)/static/ {
root /var/web2py/applications/;
}
location / {
#uwsgi_pass 127.0.0.1:9001;
uwsgi_pass unix:///run/uwsgi/app/web2py/web2py.socket;
include uwsgi_params;
uwsgi_param UWSGI_SCHEME $scheme;
uwsgi_param SERVER_SOFTWAREnginx/$nginx_version;
}
}
server {
listen 443;
server_name $hostname;
ssl on;
ssl_certificate /etc/nginx/ssl/web2py.crt;
ssl_certificate_key /etc/nginx/ssl/web2py.key;
location / {
#uwsgi_pass 127.0.0.1:9001;
uwsgi_pass unix:///run/uwsgi/app/web2py/web2py.socket;
include uwsgi_params;
uwsgi_param UWSGI_SCHEME $scheme;
uwsgi_param SERVER_SOFTWAREnginx/$nginx_version;
}
}
I am still stumped.

[web2py] Add custom class to...
I am using SQLFORM.grid and I need to wrap a big chunk of text (one of the
data elements) in a CSS class called big-chunk.
I remember it wasn't hard to add a CSS class to a dal field, but I can't
seem to find the solution.
I tried this method:
db.define_table('table',
Field('combitext', 'text', represent=lambda x,row: XML(div
class=big-chunk+x+/div) ),
),
This works great except, when displaying the full grid, the text-heavy
field would be output in a whole big chunk. Appadmin also displays the
whole text when in table format.
I tried to limit the number of characters using maxtextlengths in
SQLFORM.grid but it isn't working either (whole chunk of text appears). I
know that from this experience it proves that db.table.field.represent will
ensure that it will appear the way you want it to, but I only need it to
appear like that when I click on VIEW on the grid.
Note: I need to wrap the value of the text output (in view mode) in a
class, I do *not* need to add a class to a form field. thanks
I appreciate any help.
