Wagtail Embed Finder not matching twitter and facebook urls
I'm using Wagtail 1.12.1 and having trouble getting the oembed provider finders to match twitter, facebook post/video, and vimeo urls. There may be others but so far I have only had success with youtube and instagram urls. I encountered the problem when trying to create a StructBlock which has an EmbedBlock but also tried directly adding urls to {% embed %} tags and using the get_embed method neither of which worked with Twitter and Facebook URLs. Has anyone had success with using Facebook and Twitter embeds with the oembed finders and might know what I am doing wrong? I've tried leaving WAGTAILEMBEDS_FINDERS out of my settings, then added it will all_providers set and finally tried only importing the ones that I needed. It didn't have any effect. settings.py from wagtail.wagtailembeds.oembed_providers import youtube, twitter, vimeo, instagram, facebook_video, facebook_post, twitter, soundcloud, tumblr WAGTAILEMBEDS_FINDERS = [ { 'class': 'wagtail.wagtailembeds.finders.oembed', 'providers': [youtube, twitter, vimeo, instagram, facebook_video, facebook_post, twitter, soundcloud, tumblr] } ] An example of the Twitter StructBlock I created. blocks.py from wagtail.wagtailcore import blocks from wagtail.wagtailembeds.blocks import EmbedBlock class TwitterEmbedBlock(blocks.StructBlock): tweet_url = EmbedBlock(required=True) show_cards = blocks.BooleanBlock(required=False, default=True) show_conversation = blocks.BooleanBlock(required=False, default=True) class Meta: template = 'blog/blocks/tweet.html' When I save that I've checked the … -

Django rest framework full-text search not finding word "Will"
I'm developing a Django app with an API REST using Django REST Framework. I have implemented a search filter for the User model in which I want to use a Full-text Search for the field 'name'. It is working fine for every name or word except for word "Will" or "will". I've tried other similar words like "wall" or "well" and it just worked fine.

django - dynamic field's verbose_name/label
i am searching for the right way to implement the same model data but with different fields titles corresponding to the group the user belong to. for example: if the model field name is "text", for group1 admin will define that the verbose_name/label = "text1", so: 1. when the model form open for update "text1" will be showen. make the fields headers of the table (at the templates) that shows a model list result by the same behavior. and of course solution with good performance and cost. would much appreaciate some guidence, thanks -

Django model design to analyse user activities on external websites
I am working on an app that analyses the activities of users on some external sites. The contents of the target sites fall into three types: Forum post: A user can either start a thread or reply to an existing one, the reply will get an unique url; Blog entry: Any user can post. The blog entry gets an unique url, comments do not. News article: Not user posted, from a number of news sources. Comments do not have an unique url. The focus of my app is on user activities, below are some possible questions: How often does user A post (with respect to types, daily, weekly, etc.)? What topics are the user mostly interested in? (for this, all threads will be taged based on their original category and scanned keyword from title/content). Is user A tend to reply user B's posts then user C's? (obviously this particular question suits more on forum posts and blog entries). I plan to consolidate a Thread model to hold all three types of contents, do not address the diffrences in them, for example, theat the news source just as a regular user. The Thread model will have roughly 10 millions of records. … -

Form validation for Twilio in Django to send a SMS message
I'm trying to set up Twilio integration inside a DetailView Django page. They look at the detailed view page and can request a booking via from POST method.

However, when I submit the form, I get the following text message: Student Phone number: <bound method BoundField.value of <django.forms.boundfield.Boundfield object at 0x104e5f0b8>> Note that if I don't use forms, but instead have a simple user_phone = self.request.POST['Phone'] instead of validating the form using if form.is_valid(), everything works correctly. -

Converting static CASE WHEN statements to dynamic to supply to .annotate()
I have this ORM query that is working well.

For tat, I did the following function which simply outputs the CASE WHEN statements as a string when called. The problem is when I pass it to annotate() I get the 'str' has no 'resolve' error. Hope you get what I want to do.

Handling categories and sub categories in Django
I am working on a django project where "venues" can have a menu of food and drink items. Within this, there can be a varying number of sub menus, "Breakfast", "Lunch", "Dinner", "Drinks" etc etc. I am struggling to work out how while using django generic views to simply use a {% foreach %} to achieve this result. I do not know how many sub menus there will be in each instance or the names of them. Can anyone point me in the right direction for where to look? Or should I try to solve in python in a custom template tag? -
How to enable compression on Django project and still be safe?
We're using Python Django for our project. When I tested the website on google page speed, I saw a warning of Enable compression, Leverage browser caching, and Reduce server response time. For this post I'd like to ask regarding the Enable compression problem. I myself has no experience with GZIP compression and my backender has no experience with this as well. One thing is, he suggested not to do it due to a warning on Django site: Warning Security researchers recently revealed that when compression techniques (including GZipMiddleware) are used on a website, the site becomes exposed to a number of possible attacks. These approaches can be used to compromise, among other things, Django’s CSRF protection. Before using GZipMiddleware on your site, you should consider very carefully whether you are subject to these attacks. If you’re in any doubt about whether you’re affected, you should avoid using GZipMiddleware. For more details, see the the BREACH paper (PDF) and breachattack.com. How do I enable compression and still be safe? What do I need to do? -
