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

问题 Okay, so I am trying to get prices from an API, now the prices are found in "sell_summary", and "buy_summary", I managed to return these values to my HTML but the issue is that every item from the API, has multiple 'pricePerUnit's, so there could be up to 10 pricePerUnits in one "sell_summary" for example, I only want the top one (because that's the latest updated price). Here is my Python code: import requests from flask import Flask, render_template, url_for product_names = [this array just

问题 I am creating an app to post products to a marketplace. Each product category on this marketplace has a different form for product attributes, for example if it's electronic there are fields for voltage, model number... I get this information via json through the marketplace server. First the user has to write the name of the product and it's main category and the marketplace server predicts their own category and returns to me it's attributes. Here's an example of the response: { "id":

问题 I'm using Jinja2 and Python to generate html and I'm also using bootstrap for the css and js. I'm trying to create Bootstrap pill tabs by using Jinja2 for loops and some other logic. Here is what my code looks like: I pass this dictionary into the render_template function of flask along with the name of the html file I want to generate: my_dict = {"First tab": "tab1", "Second tab": "tab2", "Third tab": "tab3"} The keys of the dictionary represent the text that is displayed as the name of the

问题 It is possible to apply the sort filter in Jinja2 successively to sort a list first by one attribute, then by another? This seems like a natural thing to do, but in my testing, the preceeding sort is completely unstable and all sorting is lost. I already worked around it by sorting first in python before passing the list to the template, but I would like to know if it's possible to sort "stable" in Jinja2. The way I applied the filter was like so: {{ item_list|sort(attribute='value')|sort

问题 How do I escape HTML with Jinja2 so that it can be used as a string in JavaScript (jQuery)? If I were using Django's templating system I could write: $("#mydiv").append("{{ html_string|escapejs }}"); Django's |escapejs filter would escape things in html_string (eg quotes, special chars) that could break the intended use of this code block, but Jinja2 does not seem to have an equivalent filter (am I wrong here?). Is there a cleaner solution than copying/pasting the code from Django? 回答1: I

问题 I want to change the color of the message variable in the following HTML: <span id="mess" style="visibility:visible;"> <text id="tex">{{ message }}</text> </span I am using Jinja2 together with Flask - Python to pass a value to the {{ message }} variable. Here is how I tried to do it: $(document).ready(function(){ if (document.getElementById('tex').value == 'Message sent !') { document.getElementById('tex').setAttribute("style", "color:green;"); } else { document.getElementById('tex')

问题 NOTE: Original question expanded on here: Is there a way in Ansible to replace a dictionary value based on k:v lookup to another dictionary? I have 3 dictionaries, the first 2 are k:v with string:integer type values; My 3rd dictionary is a k:v of string:string which I want to loop through first with dict #1 and to replace the k with the k:v and then the same with dict #2 but replacing v with k:v. "dict_1": { "office-core01": 85, "office-core02": 86, "office-fw01": 87, "office-fw02": 88,
