Jinja2 filter

Filters in Jinja2 are a way of transforming template expressions from one kind of data into another. Jinja2 ships with many of these. See builtin filters in the official Jinja2 template documentation. In addition to those, Ansible supplies many more You can use the Ansible-specific filters documented here to manipulate your data, or use any of the standard filters shipped with Jinja2 - see the list of built-in filters in the official Jinja2 template documentation. You can also use Python methods to transform data Overview of Jinja2 filters Let's jump straight in. Jinja2 filter is something we use to transform data held in variables. We apply filters by placing pipe symbol | after the variable followed by name of the filter. Filters can change the look and format of the source data, or even generate new data derived from the input values Filter sections allow you to apply regular Jinja2 filters on a block of template data. Just wrap the code in the special filter section: {% filter upper %} This text becomes uppercase {% endfilter %} Assignments¶ Inside code blocks, you can also assign values to variables. Assignments at top level (outside of blocks, macros or loops) are exported from the template like top level macros and.

Welcome to Jinja2¶. Jinja2 is a modern and designer-friendly templating language for Python, modelled after Django's templates. It is fast, widely used and secure with the optional sandboxed template execution environment Additionally, the attr() filter only looks up attributes. Filters¶ Variables can be modified by filters. Filters are separated from the variable by a pipe symbol (|) and may have optional arguments in parentheses. Multiple filters can be chained. The output of one filter is applied to the next. For example, {{name|striptags|title}} will remove all HTML Tags from variable name and title-case. Invalid filter: 'replace' Output Jinja2 v2.8.0 aaa..bccc Output Liquid v3.0.6 aaabbbccc Output Nunjucks v2.5.0 aaa..bccc Output Swig (error) v1.4.2 Invalid flags supplied to RegExp constructor '2' Output Twig v1.24.2 aaa...ccc Output Twigjs v0.9.5 aaabbbccc Test: empty Template {{ Jinja2 is a templating engine for python.

I can use ' and {but when I replace with. Embedding Jinja2 templates in YAML files is one of Ansible's distinguishing features. This feature enables the creation of generic roles and playbooks that work without modification for multiple environments, or even multiple projects by simply overriding variables in the group_vars/ directory, the playbook, or even the command line.. Jinja2 comes with a few dozen built-in filters, and Ansible. Filters can be used for a variety of things, for example, the join() filter can be used to join all strings in a list together, like this: {{['Thi','s wi','ll b','e appended']|join}} will return This will be appended. Another example of a potentially useful filter could be the safe() filter. This filter allows us to inject JavaScript and HTML. Jinja2 comes with many built-in filters A filter is applied to a variable by way of the pipe symbol (|) followed by the name of the filter and then any arguments for the filter inside parentheses. There can be a space between the variable name and the pipe symbol as well as a space between the pipe symbol and the filter name

The core component of Jinja is the Environment.It contains important shared variables like configuration, filters, tests. Advancing in Ansible: ternary (Jinja2 filter) Ansible version 1.9 introduced the ternary filter. This filter is one of the most useful filters, in my opinion. It can be overused, but typically what ends up happening is instead of using | ternary () a huge amount of logic gets baked into other stuff (with_items, set_fact) instead; so I prefer it

Using custom template filters in Jinja2 by Hiten Pratap

  1. Jinja2's built-in filters Aside from basic language features, Jinja2 has (at the time of writing) 50 built-in filters. These are documented here. Some of them are useful for text manipulation, such as the center and wordwrap filters
  2. Ansible uses Jinja2 which is a modern templating engine for Python frameworks used to generate dynamic content or expressions. Templating is extremely useful when creating custom configuration files for multiple servers but unique for each of them. Jinja2 uses the double curly braces { {... }} to enclose a variable that has been defined
  3. Creating a Custom Jinja2 Filter After looking at the above example, experienced developers might think that it was stupid to use a context processor for the purpose. One can simply write a filter to get the same result; this will make things much cleaner. A filter can be written to display the descriptive name of the product as shown below
  4. Jinja2 template with filters. Filters are used to alter the appearance of output or formatting data. This works by piping the variable name as shown: {{ variable | argument }} Let's check out a few use cases: a) Transform strings into either Uppercase or lowercase format. For example, to print the values in the previous list in uppercase characters using the template, pipe the variable item.

I recently wrote this article about exploring the true impact of Server-Side Template Injection (SSTI) in applications leveraging the Flask/Jinja2 development stack. My initial goal was to find a path to file or operating system access. I was previously unable to do so, but thanks to some feedback on the initial article, I have since been able to achieve my goal Jinja2 provides a filter for this purpose. It will return a string which is the result of concatenating all the string in the list. For example, to join 4 values in the previous example, you can do the following. - hosts: all vars: test: ['192','168','14','21'] tasks: - debug: msg: {{ test | join('.') }} output ----- ok: [localhost] => { msg: } Ansible Modules. Post. Jinja2 'ipaddr()' filter ¶ New in version 1.9. ipaddr() is a Jinja2 filter designed to provide an interface to netaddr Python package from within Ansible. It can operate on strings or lists of items, test various data to check if they are valid IP addresses and manipulate the input data to extract requested information. ipaddr() works both with IPv4 and IPv6 addresses in various forms. If you want to register your own filters in Jinja2 you have two ways to do that. You can either put them by hand into the jinja_env of the application or use the template_filter() decorator. The two following examples work the same and both reverse an object: @app. template_filter ('reverse') def reverse_filter (s): return s [::-1] def reverse_filter (s): return s [::-1] app. jinja_env.

  3. The concepts of tags and filters exist both in the Django template language and in Jinja2 but they're used differently. Since Jinja2 supports passing arguments to callables in templates, many features that require a template tag or filter in Django templates can be achieved by calling a function in Jinja2 templates, as shown in the example above. Jinja2's global namespace removes the need.

class jinja2.nodes.Filter(node, name, args, kwargs, dyn_args, dyn_kwargs)¶ This node applies a filter on an expression. name is the name of the filter, the rest of the fields are the same as for Call. If the node of a filter is None the contents of the last buffer are filtered. Buffers are created by macros and filter blocks The jinja2 template gives us a lot of filter options, but we can also define the filters ourselves. First we need to configure the filters needed for in the py file. Everything is for business, and the code is also the need to implement the business. It should be noted that we have parameters in the function, this parameter is similar to the parameters required by the filter in jquery. We'll use the Jinja2 templating language to generate each file from a base template. Our particular example will be the generation of Logstash filters for log processing, but the techniques for using JSON to drive Python processing or Jinja2 templating within Python are general purpose. Logstash Filters Explaine ansible playbook with jinja2 loop Hot Network Questions Are Landlord's exclusion clauses of any loss of life or loss, injury or damage to person or property too onerous on Tenant You must filter the value through the safe filter to tell jinja2 that it shouldn't apply any other filters to the output. In jinja2 syntax this would be: {{ jsonData | safe }} Note that since you are calling json.loads you actually do not have json data anymore, you have a python list object. Thus when it is serialized it's the same as calling unicode(['dogs', 'cats']) which is going to give.

Even though we've not yet discovered a way to escape the template sandbox, we've made some headway in determining the impact of SSTI in the Flask/Jinja2 development stack. I'm certain that there is some additional digging to do here, and I intend to continue, but I encourage others to dig in and explore as well. I'll update things here if/when I find additional items of interest. Flask Custom Jinja2 Template Filters.

The idea is that if a developer already knows Jinja2 from working with one project then the. Registering Filters¶ If you want to register your own filters in Jinja2 you have two ways to do that. You can either put them by hand into the jinja_env of the application or use the template_filter() decorator. The two following examples work the same and both reverse an object Running a for-loop over a Jinja2 dictionary At the time of this posting, iterating over dictionaries inside a Jinja template is poorly documented, especially if you need access to the jinja dictionary keys and it's something I end up doing alot. Of course running a for-loop over a jinja dictionary is as basic an activity as you're likely to do, for whatever reason it's buried in the Jinja2. This is important if an object has an item and attribute with the same name. Additionally, the attr() filter only looks up attributes. Conclusion & Contact. I hope this post clarified certain concepts, and helps people get into SSTI payloads for Jinja2, as they are extremely satisfying to make

Jinja2 has built in filter and I can use those, upper, lower and so on. So, why not make your filter and use the form {{ data.address | netmask }} Something like this: def netmask (ipaddress): converts the given ip address and prefix length to classic netmask format try: ip = IPv4Network(ipaddress) return ip. netmask. But were do I put this in Netbox and how will it survive an update. Jinja2 builds off of Django supporting additional filters, tags, and functionality that gives it more power.
