I have some filenames stored with the # symbol. If I send a GET request to retrieve them I am running into problems as I believe GET requests are cut off at anchors within the path?
ex:
s3.amazonaws.com/path/to/my_file.jpg
vs: my browser stops looking at the #
s3.amazonaws.com/path/to/my_other_#file.jpg
is there a way to retrieve the file or will I have to change filenames so they do not contain #'s?
You need to encode your path as URL which would replace # with %23.
Check out this for URL encoding. https://www.w3schools.com/tags/ref_urlencode.asp
In JavaScript you can use encodeURI() to get it encoded.

I have a website building tool created in Django and I'd like to add easy user defined 301 redirects to it.
Webflow has a very easy to understand tool for 301 redirects. You add a path (not just a slug) and then define where that path should lead the user.
I'd like to do the same for the Django project I'm working on. I currently allow users to set a slug that redirects /<slug:redirect_slug>/ and they can set to go to any URL. But I'd like them to be able to add, for example, the path for an old blog post '/2018/04/12/my-favorite-thing/'
What's the best URL conf to use in Django to safely accept any path the user wants?
You can use the Path Converters that convert the path parameters into appropriate types, which also includes a converter for urls.
An example would be like the following:
path('api/<path:encoded_url>/', YourView.as_view()),
As per the docs:
Matches any non-empty string, including the path separator, '/'. This allows you to match against a complete URL path rather than just a segment of a URL path as with str.
In your view, you can get your URL like this:
encoded_url = self.kwargs.get('encoded_url')
Add a RerouteMiddleware which first checks if the request can be served by the existing URLs from the urls.py. If it cannot be served, check if the requested path is from the old -> new URLs mapping, if a match found redirect it to the new URL.
Sample piece of code to try it out.
try:
resolve(request.path_info)
except Resolver404:
# Check if the URL exists in your database/constants
# where you might have stored the old -> new URL mapping.
if request.path is valid:
new_url = # Retrieve the new URL
return redirect(new_url)
response = self.get_response(request)
return response
I'm trying to write my own Jekyll plugin to construct an api query from a custom tag. I've gotten as far as creating the basic plugin and tag, but I've run into the limits of my programming skills so looking to you for help.
Here's my custom tag for reference:
{% card "Arbor Elf | M13" %}
Here's the progress on my plugin:
module Jekyll
class Scryfall < Liquid::Tag
def initialize(tag_name, text, tokens)
super
#text = text
end
def render(context)
# Store the name of the card, ie "Arbor Elf"
#card_name =
# Store the name of the set, ie "M13"
#card_set =
# Build the query
#query = "https://api.scryfall.com/cards/named?exact=#{#card_name}&set=#{#card_set}"
# Store a specific JSON property
#card_art =
# Finally we render out the result
"<img src='#{#card_art}' title='#{#card_name}' />"
end
end
end
Liquid::Template.register_tag('cards', Jekyll::Scryfall)
For reference, here's an example query using the above details (paste it into your browser to see the response you get back)
https://api.scryfall.com/cards/named?exact=arbor+elf&set=m13
My initial attempts after Googling around was to use regex to split the #text at the |, like so:
#card_name = "#{#text}".split(/| */)
This didn't quite work, instead it output this:
[“A”, “r”, “b”, “o”, “r”, “ “, “E”, “l”, “f”, “ “, “|”, “ “, “M”, “1”, “3”, “ “]
I'm also then not sure how to access and store specific properties within the JSON response. Ideally, I can do something like this:
#card_art = JSONRESPONSE.image_uri.large
I'm well aware I'm asking a lot here, but I'd love to try and get this working and learn from it.
Thanks for reading.
Actually, your split should work – you just need to give it the correct regex (and you can call that on #text directly). You also need to escape the pipe character in the regex, because pipes can have special meaning. You can use rubular.com to experiment with regexes.
parts = #text.split(/\|/)
# => => ["Arbor Elf ", " M13"]
Note that they also contain some extra whitespace, which you can remove with strip.
#card_name = parts.first.strip
#card_set = parts.last.strip
This might also be a good time to answer questions like: what happens if the user inserts multiple pipes? What if they insert none? Will your code give them a helpful error message for this?
You'll also need to escape these values in your URL. What if one of your users adds a card containing a & character? Your URL will break:
https://api.scryfall.com/cards/named?exact=Sword of Dungeons & Dragons&set=und
That looks like a URL with three parameters, exact, set and Dragons. You need to encode the user input to be included in a URL:
require 'cgi'
query = "https://api.scryfall.com/cards/named?exact=#{CGI.escape(#card_name)}&set=#{CGI.escape(#card_set)}"
# => "https://api.scryfall.com/cards/named?exact=Sword+of+Dungeons+%26+Dragons&set=und"
What comes after that is a little less clear, because you haven't written the code yet. Try making the call with the Net::HTTP module and then parsing the response with the JSON module. If you have trouble, come back here and ask a new question.
Working on a Django/React app. I have some verification emails links that look like the following:
https://test.example.com/auth/security_questions/f=ru&i=101083&k=7014c315f3056243534741610545c8067d64d747a981de22fe75b78a03d16c92
In dev env this works fine, but now that I am getting it ready for production, it isn't working. When I click on it, it converts it to:
https://test.example.com/auth/security_questions/f%3Dru&i%3D101083&k%3D7014c315f3056243534741610545c8067d64d747a981de22fe75b78a03d16c92/
This prevents react-router-dom from matching the correct URL, so a portion of the web application does not load properly.
The link is constructed using the following.
link = '%s/auth/security_questions/f=%s&i=%s&k=%s' % \
('https://test.example.com', 'ru', user.id, user.key)
Also, here is the url() that is catching the route:
url(r'^(?:.*)/$', TemplateView.as_view(template_name='index.html')),
These variables are supposed to be query parameters in a GET request. When you construct the link, you'll need to have a question mark in there somewhere separating the URL from the query string:
https://test.example.com/auth/security_questions/?f=ru&i=101083&k=7014c315...

The conversion of = to url-encoded %3D etc is correct, and equivalent. Sometimes variables are part of the URL directly, but webapps don't use &-separated key/value pairs in that case.
I have a URL in the form of:
http://some-site.com/api/v2/portal-name/some/webservice/call
The data I want to fetch needs
http://portal-name.com/webservices/v2/some/webservice/call
(Yes I can rewrite the application so it uses other URL's but we are testing varnish at the moment so for now it cannot be intrusive.)
But I'm having trouble getting the URL correctly in varnish VCL. The api part is replaced by an empty string, no worries but now the portal-name.
Things I've tried:
if (req.url ~ ".*/(.*)/") {
set req.http.portalhostname = re.group.0;
set req.http.portalhostname = $1;
}
From https://docs.fastly.com/guides/vcl/vcl-regular-expression-cheat-sheet and Extracting capturing group contents in Varnish regex
And yes, std is imported.
But this gives me either a
Syntax error at
('/etc/varnish/default.vcl' Line 36 Pos 35)
set req.http.portalhostname = $1;
or a
Symbol not found: 're.group.0' (expected type STRING_LIST):
So: how can I do this? When I have extracted the portalhostname I should be able to simply do a regsub to replace that value with an empty string and then prepend "webservices" and my URL is complete.
The varnish version i'm using: varnish-4.1.8 revision d266ac5c6
Sadly re.group seems to have been removed at some version. Similar functionality appears to be accessible via one of several vmods. See https://varnish-cache.org/vmods/
When upload image, vtiger add prefix to filename.
Befor upload: IMG_NAME.png.
After upload: 26540_IMG_NAME.png.
How I can remove '26540_' prefix?
Its not recommended to change the standard of storing files with the name. Because the prefix ('26540_' in your case) is the unique identifier which will add before the filename. And if we upload same file with the same name vTiger treat as a different file.
But still if you dont want to prefix added then customize the code as per below:
Open \data\CRMEntity.php
Search function uploadAndSaveFile(
Comment the line
$upload_status = move_uploaded_file($filetmp_name, $upload_file_path .$current_id . "_" . $binFile);
Add (Removed $current_id)
$upload_status = move_uploaded_file($filetmp_name, $upload_file_path . $binFile);
Save the script and test. Cheers!
