Bug report

[Radek]

Hi makoto kuwata

I found a strange behavior.

What's wrong on following code

#{ {True: 'checked', False: 'unchecked'}[role in user.roles] }

In ipython it looks good. But in Tenjin I got an error.
_buf.extend((''' />
''', to_str( {True: 'checked', False: 'unchecked'), '''[role in
user.roles] }

Is there any workarround?

My first code was:
<?py if role in user.roles: ?>
checked
<?py #endif ?>
but I like to be more compact
#{ {True: 'checked', False: ''}[role in user.roles] }

It is not allowed to include '}' inside of ${...}. This is a
limitation of pyTenjin.
Please try:

<?py d = {True: 'checked', False: 'unchecked'} ?>
#{d[role in user.roles]}

Or if you use pyTenjin 1.0.1:

{= {True: 'checked', False: 'unchecked'}[role in user.roles] =}

Thank you, now I rewrote it to:

${role}<input type="checkbox" name="roles" value="${role}"
{= {True: 'checked', False: ''}[role in user.roles] =} />

instead old version:

${role}<input type="checkbox" name="roles" value="${role}"

<?py if role in user.roles: ?>
checked
<?py #endif ?>

/>

I just upgraded PyTenjin yesterday to 1.0.1. But didn't check the
documentation, my mistake.


So, thanks for help.

Tenjin provides HTML helper which prints 'checked="checked"'.

## main program
from tenjin.html import *

## html template
<input type="checkbox" #{checked(role in user.roles)} />

In addition, tenjin.html.nv() makes your code shorter.

<input type="checkbox" #{nv('role', role, checked=(role in user.roles))} />

Output:
## if (role in user.roles) == True:
<input type="checkbox" name="role" value="..." checked="checked" />
## else:
<input type="checkbox" name="role" value="..." />
