Okay, done :) 
(Assuming that Python code in {{...}} can't access anything from Javascript 
on the page - and here encode URI came into play, as per your earlier 
advice)

var id = $('#CurrentCartId').text();
var description = $(this).text();
var url='{{=URL('cart','description')}}';
url += '/' + id + '/';
url += "?description="+description;
url=encodeURI(url);
ajax(url,[],':eval');

Re: [web2py] Re: A question about ajax function (passing a string parameter over)

2019-05-18 Thread Vlad 
Oops, I still don't know how to achieve it. Here is why: 

This is from the javascript code on the page: 

var description = $(this).text();
var 
url='{{=URL('cart','description'),args=[id],vars=[dict(description=description)]}}';

So, the variable description belongs to javascript, and it's presumably 
impossible to access it in {{...}} sections, unless I am missing something. 
Any code in {{...}} is executed and built on the server side, and then 
delivered to the browser, so while on the server, those javascript 
variables are inaccessible. OR is there a way to somehow access them 

Of this is this case, then I am stuck to having var 
url='{{=URL('cart','description')}} and then url += description, hence I 
now have to use encoding/decoding solution... 

Is there a way to solve this without encoding / decoding???

Re: [web2py] Re: A question about ajax function (passing a string parameter over)

2019-05-18 Thread Eliezer (Vlad) Tseytkin 
Here is a test I've just run:

def test():
url = URL('cart','test2',args=['a b c 1 3 2 $ % ( ) !'],vars={'oops':'1
3 5  a s i t ! @ #  $ %'})
redirect(url)

def test2():
str1 = request.args[0]
str2 = request.vars['oops']
return locals()

Here is what it displays as a result:

{{extend 'layout.html'}}
{{=str1}}

{{=str2}}

a_b_c_1_3_2__
1 3 5 a s i t ! @ # $ %

Obviously, this proves that you're right, and my mistake in the beginning
was that I didn't try vars - I simply tried args, and saw right away that
args distorts the string. I mistakenly assumed that vars works the same way
- and didn't even try it. This is how I got into conversion business...

Anyway, thank you very much for all your help and for patience!

Okay, I got it :)

Very embarrassing. There were some prior entries in the database that
weren't converted to begin with, so when they were pulled over, the
exception was raised. I totally forgot about them, and on top of that the
one that caused the trouble was just one character different from the one I
was testing against, with 49 characters being the same, so it was almost
unnoticeable visually...

I thought that the conversion malfunctioned, while in fact it simply pulled
back something else, without me realizing what was going on...

I took a deep breath and patiently went through the whole thing step by
step and, of course, found it. It's now just perfect. Ended up using atob
and btoa.

Just a quick question: are atob and btoa consistent and give the same
results across browsers and operating systems? (If not, I'll use that uri

[web2py] Re: A question about ajax function (passing a string parameter over)

2019-05-17 Thread Vlad 
I'll try to simplify it, hoping that I'll figure it out, but it's really 
very puzzling: 

this works perfect: 

var encodedDescription = $("#CurrentCartDescription").text();
$("#CurrentCartDescription").html(atob(encodedDescription));

it decodes it back just exactly from what it was encoded. 
However, the following is messed up: 

$(".EncodedDescriptionField").each( function(index, element ){
 var hereWeAre = $(this).text();
 var decodedString = atob(hereWeAre);
 console.error(hereWeAre);
 console.error(decodedString); 
});

throws an exception, even for the same very value! 

Will simplify it all now, let's see what comes out...

It works almost, but not 100% :) 

with encodeURIComponent :

abc def (test)
comes back as
abc_def__test_

a;slkdjf;l -239i4-29i23la'skfj(()))9012?  <>,.  =
comes back as
a_slkdjf_l_-239i4-29i23la_skfj_9012__.__=

This wouldn't help me, because I want it to be exactly whatever they enter 
- 

In contrast, atob and btoa work just perfect, except that in one particular 
situation is gets messed up by that exception...

How about putting the variables in the query string:

const id = $('#CurrentCartId').text();
const description = $(this).text();
const url='{{=URL('cart','description')}}';
ajax(
`${url}?id=${encodeURIComponent(id)}&description=${encodeURIComponent(description)}`
, [], ':eval');

Then in the controller, access request.vars.id and request.vars.description.

Make sure that your jQuery loading and browser up to date...

Simplify the page to something like below.  Get that working.  Add back 
your complexity afterwards:

Q29va2llcyBvbmU=


$(".EncodedDescriptionField").each( function(index, element ){
 var hereWeAre = $(this).text();
 alert(hereWeAre);
 var decodedString = atob(hereWeAre);
 console.log(decodedString); 
});

 this brings up an exception: 

 Uncaught DOMException: Failed to execute 'atob' on 'Window': The string

 I've also double-checked the values - they are correct. For example, 
 when I replace with the following: 

  var decodedString = atob("Q29va2llcyBvbmU=");

 it decodes just fine, and the string itself I pick right from there - 
 that's the value it has when it throws exception. 

 Have no slightest clue what could possibly go wrong.

 Obviously, it needs to do this conversion in order to pass  the

 Is there a better way of doing this? I.e. a better way of passing a
 parameter in  a way that it could be "recreated" and stored in the 
 database
 exactly as typed by the user?

Those are span elements inside  inside in a table.

But the values themselves are fine - I can print them out, and they are
correct. It's only a problem when I try to apply btoa function to it.

Hmm, not sure.  
Are you getting the values from  elements?
Try:  

var hereWeAre = $(this).val();

 Thank you very much for point to the direction. After some googling, it 
 is almost working. 

 Encoding is just fine (using btoa). 

 When I read it back and want to decode - it's not yet behaving right. 
 I'm suspecting my javascript is a problem. 

 There is a bunch of fields which now have encrypted values (class 
 'EncodedDescriptionField'), and I am trying to use the following to 
 reclaim 
 the original values: 


 $(".EncodedDescriptionField").html(atob($(".EncodedDescriptionField").text()));

 What am I doing wrong? (It doesn't change the values - they remain as 
 they are, encrypted)

 var hereWeAre = $(this).text();
 var decodedString = atob(hereWeAre);
 console.error(hereWeAre);
 console.error(decodedString); 
});

this brings up an exception: 

Uncaught DOMException: Failed to execute 'atob' on 'Window': The string to

Maybe you need to iterate through the class elements.  See this:

 I have the following javascript in the view:

 var url='{{=URL('cart','description')}}';

 ajax(url,[],':eval');

 the reason I use url+= to pass parameters instead of using args in the 
 URL helper is because the parameters are coming from the html itself - 
 they 
 are not known in the controller py. 

 now the problem is that it changes the description and I have no way to 
 recover its original value. for example, when description is "askjdf d  
  dka;lskdj  3838&^&%$#@ ((alksjdf__ - ))" (just a randomly typed string in 
 this case), it comes out as "askjdf_d___dka_lskdj__3838_". Obviously, 
 it needs to do this conversion in order to pass  the parameter, but I need 
 to be able to recreate the original string, entered by the user. 

 Is there a better way of doing this? I.e. a better way of passing a 
 parameter in  a way that it could be "recreated" and stored in the 
 database 
 exactly as typed by the user?

Just to clarify: 

the following works perfect  for one field by ID (decrypts it back):
var encodedDescription = $("#CurrentCartDescription").text()
$("#CurrentCartDescription").html(atob(encodedDescription));

However, when I try to do it for a bunch of fields at once using class 
(instead of id), it doesn't work - doesn't touch the values: 
$(".EncodedDescriptionField").html(atob($(".EncodedDescriptionField").text()));

I am sure I am missing something basic... Greatly appreciate suggestions -

[web2py] Re: A question about ajax function (passing a string parameter over)

2019-05-16 Thread Vlad 
I had no clue about it - I mean never heard the terms :)

Thank you very much for point to the direction. After some googling, it is 
almost working. 

Encoding is just fine (using btoa). 

When I read it back and want to decode - it's not yet behaving right. I'm 
suspecting my javascript is a problem. 

There is a bunch of fields which now have encrypted values (class 
'EncodedDescriptionField'), and I am trying to use the following to reclaim 
the original values: 

$(".EncodedDescriptionField").html(atob($(".EncodedDescriptionField").text()));

What am I doing wrong? (It doesn't change the values - they remain as they 
are, encrypted)
