Sometimes I use the following workaround with a temporary placeholder string: var variable1 = “someString”; $(‘#demo’).load( “{{ url_for(‘addshare2′, share=”ADDSHARE2″) }}”.replace(“ADDSHARE2”, variable1) ); It doesn’t feel quite right and I’m still looking for a better solution. But it does the job.
The problem is that {{ ‘1.1.1.1’ }} renders as 1.1.1.1 Quotes are not included. JavaScript tries to parse this as a number and can’t. Fortunately, Flask includes a Jinja filter for this. var tmp = {{ value|tojson }}; tojson will include quotes around strings and omit them for numeric values. The filtered value, when rendered … Read more
For those using Flask, put this in your __init__.py: def clever_function(): return u’HELLO’ app.jinja_env.globals.update(clever_function=clever_function) and in your template call it with {{ clever_function() }}
Per Ansible FAQ: Another rule is ‘moustaches don’t stack’. We often see this: {{ somevar_{{other_var}} }} The above DOES NOT WORK, if you need to use a dynamic variable use the hostvars or vars dictionary as appropriate: {{ hostvars[inventory_hostname][‘somevar_’ + other_var] }} So in your case: – debug: msg={{hostvars[inventory_hostname][Component].community_release_num}} Or: – debug: msg={{vars[Component].community_release_num}} Or (since … Read more
You could use loop.index: {% for i in p %} {{ loop.index }} {% endfor %} Check the template designer documentation. In more recent versions, due to scoping rules, the following would not work: {% set count = 1 %} {% for i in p %} {{ count }} {% set count = count + … Read more
To filter a list of dicts you can use the selectattr filter together with the equalto test: network.addresses.private_man | selectattr(“type”, “equalto”, “fixed”) The above requires Jinja2 v2.8 or later (regardless of Ansible version). Ansible also has the tests match and search, which take regular expressions: match will require a complete match in the string, while … Read more
You have some options. 1) Change the delimiter notation for Angular: var app = angular.module(‘Application’, []); app.config([‘$interpolateProvider’, function($interpolateProvider) { $interpolateProvider.startSymbol(‘{a’); $interpolateProvider.endSymbol(‘a}’); }]); Whatever is chosen for the start and end symbols will act as the new delimiters. In this case, you would express a variable to Angular using {a some_variable a}. This approach has the … Read more
You can use {{ variable }} anywhere in your template, not just in the HTML part. So this should work: <html> <head> <script> var someJavaScriptVar=”{{ geocode[1] }}”; </script> </head> <body> <p>Hello World</p> <button onclick=”alert(‘Geocode: {{ geocode[0] }} ‘ + someJavaScriptVar)” /> </body> </html> Think of it as a two-stage process: First, Jinja (the template engine … Read more
Everything inside the {{ … }} is a Python-like expression. You don’t need to use another {{ … }} inside that to reference variables. Drop the extra brackets: <h1>you uploaded {{ name }}<h1> <a href=”https://stackoverflow.com/questions/32024551/{{ url_for(“moremagic’, filename=name) }}”>Click to see magic happen</a> (Note that the url_for() function takes the endpoint name, not a URL path; … Read more
To turn off autoescaping when rendering a value, use the |safe filter. {{ something|safe }} Only do this on data you trust, since rendering untrusted data without escaping is a cross-site scripting vulnerability.
