Inspiration Library for Merlin AI Jinja Assistant

This article showcases examples of best practices for generating Jinja code from a natural language query and thereby simplifying your dynamic content implementation. It's important to understand that the Jinja code generated corresponds directly to the details in your natural language query. To achieve optimal results, ensure your natural language queries are structured, include the exact attribute names, and relevant details regarding the desired dynamic content.

Example

❌ A bad Jinja description:

Titles & descriptions from similar items. Truncate descriptions if descriptions are over 50 characters.

✅ A good Jinja description:

Show 6 titles & descriptions from Product Set Similar_Items. Truncate descriptions to a length of over 50 characters.

Inspiration Library

With Merlin AI Jinja Assistant, you can create dynamic content with ease. The following are some examples of natural language queries and their corresponding Jinja code outputs. These examples can provide inspiration for crafting your own detailed natural language requests for optimal Jinja code generation.

Dynamic Content Custom Solution
Print all the values from the event attribute["Product Titles"] of array data type.
Jinja
{% for title in EventAttribute['Product Titles'] %} {{ title }} {% endfor %}
Print the first value of EventAttribute["Product Titles"] of array data type only if its value is 'Tshirt'.
Jinja
{% if EventAttribute['Product Titles'][0] == 'Tshirt' %}{{ EventAttribute['Product Titles'][0] }}{% endif %}

 
Print the first 10 product titles from the ProductSet.CouponCode of object data type. If there are not enough products in the product set, use the ProductSet. DemoRecommendations to add more products such that the complete list of titles from both product sets is 10.
Jinja
{% set products = ProductSet.CouponCode[:10] %}
{% if products|length < 10 %}
{% set additional_products = ProductSet.DemoRecommendations[:10 - products|length] %}
{% set products = products + additional_products %}
{% endif %}
{% for product in products %}
{{ product.title }}
{% endfor %}

 

Fetch ProductSet DemoRecommendations. Check if it exists, and if it exists, print the title from the ProductSet, but a maximum of 5, and truncate to 20 characters.
Jinja
{% if ProductSet.DemoRecommendations %}
    {% for product in ProductSet.DemoRecommendations[:5] %}
        {{ product.title[:20] + '...' if product.title|length  20 else product.title }}
    {% endfor %}
{% endif %}

 
From ProductSet DemoRecommendations, check if it exists, and for ProductSet DemoRecommendations, fetch Product Title and Product Price, but only the odd number, and add a serial number as well.
Jinja
{% if ProductSet.DemoRecommendations %}
    {% for product in ProductSet.DemoRecommendations %}
        {% if loop.index is odd %}
            {{ loop.index }}. {{ product.title }} - {{ product.price }}
        {% endif %}
    {% endfor %}
{% endif %}

 
Check ProductSet CouponCode if it exists, and for ProductSet CouponCode fetch Product price, which should be the discounted price by 50%.
Jinja
{% if ProductSet.CouponCode %}  
{% for product in ProductSet.CouponCode %}  
{{ product.price * 0.5 }}  
{% endfor %}  
{% endif %}

 
Fetch ProductSet CouponCode if it exists for ProductSet CouponCode. Check if the product title count is 6, then fetch 6 product titles. In case the number of products is less than 6, run the other ProductSet DemoRecommendations and fetch the last remaining products from this ProductSet DemoRecommendations. In case both product sets have the same product, display only one product.
Jinja
{% set displayed_titles = [] %}
{% if ProductSet.CouponCode %}
{% for product in ProductSet.CouponCode %}
{% if displayed_titles|length < 6 and product.title not in displayed_titles %}
{{ product.title }}
{% set _ = displayed_titles.append(product.title) %}
{% endif %}
{% endfor %}
{% endif %}
{% if displayed_titles|length < 6 and ProductSet.DemoRecommendations %}
{% for product in ProductSet.DemoRecommendations %}
{% if displayed_titles|length < 6 and product.title not in displayed_titles %}
{{ product.title }}
{% set _ = displayed_titles.append(product.title) %}
{% endif %}
{% endfor %}
{% endif %}

 
What kind of personalization can I use with the Product set DemoRecommendations? I want only one product. Can you add the price also?
Jinja
{% if ProductSet.DemoRecommendations %}
  {% for product in ProductSet.DemoRecommendations[0:1] %}
    {{ product.title }} - {{ product.price }}
  {% endfor %}
{% endif %}

 
Please create Jinja code to create a condition to check whether the value from the UserAttribute data type is a string or an array of strings.
Jinja
{% if UserAttribute is string %}
  
{% elif UserAttribute is sequence and UserAttribute[0] is string %}
  
{% endif %}

 
Correct this JINJA {% if ProductSet.DemoRecommendations %} {% for product in ProductSet.DemoRecommendations[:5] %} {{ product.[:20] + '...' if product.title|length > 20 else product.title }} {% endfor %} {% endif %}
Jinja
{% if ProductSet.DemoRecommendations %}
  {% for product in ProductSet.DemoRecommendations[:5] %}
    {{ product.title[:19] + '...' if product.title|length > 20 else product.title }}
  {% endfor %}
{% endif %}

 

How can I get the current time in the format HH:MM:SS?
Jinja
{{ '%H:%M:%S' | today() }}

 

I need a program that can extract the EventAttribute Delivery Date, format it to dd/mm/yyyy format, calculate the number of days difference from today's date in IST timezone, and handle conditional checks to see if the difference is greater than or equal to 2 days or less than 2 days. Remember the date. The Delivery Date could be of the future or the past, but you should consider the absolute difference.
Jinja
{% set date = EventAttribute['Delivery Date'] %}
{% set now = '%d/%m/%Y'|today('IST') %}
{% set diff = (EventAttribute['Delivery Date']|dateFormatter('%d/%m/%Y')|days('%d/%m/%Y'|today('IST')))|abs %}
{% if diff = 2 %}
    {{ ""Difference is greater than or equal to 2 days."" }}
{% else %}
    {{ ""Difference is less than 2 days."" }}
{% endif %}

 

I want a datetime formatter that will give me the difference between two dates.
Jinja
{% set date1 = UserAttribute['Date1'] %}
{% set date2 = UserAttribute['Date2'] %}
{% set diff = date1|dateFormatter('%d/%m/%Y')|days(date2|dateFormatter('%d/%m/%Y')) %}
{% set year = diff // 365 %}
{% set month = (diff - (year * 365)) // 30 %}
{% set day = diff - (year * 365) - (month * 30) %}
{{ year }} Years, {{ month }} Months, {{ day }} Days

 

Fetch the title from the product sets CouponCode. If there are duplicate descriptions, remove them by keeping only the first value. Finally, print only the unique titles and descriptions.
Jinja
{% set unique_titles = [] %}
{% set unique_descriptions = [] %}
{% if ProductSet.CouponCode %}
    {% for product in ProductSet.CouponCode %}
        {% if product.description not in unique_descriptions %}
            {{ unique_titles.append(product.title)|replace('None', '') }}
            {{ unique_descriptions.append(product.description)|replace('None', '') }}
        {% endif %}
    {% endfor %}
{% endif %}
{% for i in range(0, unique_titles|length) %}
    {{ unique_titles[i] }}: {{ unique_descriptions[i] }}
{% endfor %}

 

Print the first name.
Jinja
{{ UserAttribute['First Name'] }}

 
We have the following SMS that we would need support for Event Attribute 'currency' and 'Order Value' to be delivered in Jinja. Hi. Your payment for {{Order Value}} was declined, as your credit card is currently suspended. Rules 1. Main currencies would need to be formatted with the symbol instead as: GBP = £, USD = $, AUD = $, EUR = € (Important: No spaces between currency symbol and 'amount'. Example, €8.00). Any other currency code that could be coming in the payload would maintain its currency code. Example, AED 8.00 (Important: SPACE between currency symbol and 'Order Value') 2. 'Order Value' must be formatted with 1000s separation. For example, 1,989, 12,986, 123,098, etc.

 
Jinja
{% set currency_symbols = {'GBP': '£', 'USD': '$', 'AUD': '$', 'EUR': '€'} %}
{% set currency_symbol = currency_symbols.get(currency, currency) %}
{% if currency in currency_symbols %}
    {% set formatted_amount = amount|string|replace(',', '')|int|format('%0,.2f') %}
    {% set display_amount = currency_symbol ~ formatted_amount %}
{% else %}
    {% set formatted_amount = amount|string|replace(',', '')|int|format('%0,.2f') %}
    {% set display_amount = currency_symbol ~ ' ' ~ formatted_amount %}
{% endif %}
Hi. Your payment for {{ Order Value }} was declined, as your credit card is currently suspended. Please see the email we sent you, or get in touch if you need help.

 
Concatenate the first and second value of event attribute["Product Titles"], which is of array data type, with a '+'. If the concatenated value is greater than 5 characters, print 5 characters of the concatenated string and append '...' at the end.
Jinja
{% set concatenated = EventAttribute['Product Titles'][0] ~ '+' ~ EventAttribute['Product Titles'][1] %}
{% if concatenated|length  5 %}
    {{ concatenated[:5] ~ '...' }}
{% else %}
    {{ concatenated }}
{% endif %}

 

"Fix this Jinja

{% set target_date = '13/03/2025' %}
{% set today_date = '%d/%m/%Y'|today('EST') %}
{% set diff = target|days(today_date) %}
{{ diff }} Days"
Jinja
{% set target_date = '13/03/2025' %}
{% set today_date = '%d/%m/%Y'|today('EST') %}
{% set diff = target_date|days(today_date) %}
{{ diff }} Days

 
Remove the tailing decimal zeros of the Event Attribute "Order Value", which is of float data type and then convert the data type from float to string.
Jinja
{% set value = EventAttribute['Order Value'] %} {% set formatted_value = ('%.15g' % value)|string %} {{ formatted_value }}
