问题 I need to get content from particular block in Jinja2 by console script.

Jinja2: format + join the items of a list

由 主宰稳场 提交于 2020-06-24 20:32:12
问题 play_hosts is a list of all machines for a play. I want to take these and use something like format() to rewrite them like rabbitmq@%s and then join them together with something like join() . So: {{ play_hosts|format(???)|join(', ') }} All the examples of format use piping where the input is the format string and not a list. Is there a way to use these (or something else) to accomplish what I want? The output should looks something like: ['rabbitmq@server1', 'rabbitmq@server2', rabbitmq

由 你。 提交于 2020-06-24 05:44:09

WTForms TextAreaField DataRequired not raising validation error in Bootstrap modal

由 妖精的绣舞 提交于 2020-06-09 04:21:22
问题 I have a very small form in a bootstrap modal including just two fields: a TextAreaField and a Submit button. My TextAreField is DataRequired . On top of that this field uses CKEditor (similar to quillsJS) to make the text area WYSIWYG. Problem is that the form submits even when no data has been entered, and reloads the parent page. I would very much like to know how to prevent that form submission and raise the validation error when no data has been entered. I would like to get WTForm
