ComfyUI Node: Prompt from template 🪴

Prompt from template 🪴:

The "Prompt from template 🪴" node is designed to help you generate dynamic and varied text prompts based on a predefined template. This node is particularly useful for AI artists who want to create diverse and creative prompts without manually writing each one. By using a template with placeholders, you can automatically replace these placeholders with random or specific items from predefined lists, making your prompt generation process more efficient and creative. The node leverages a seed value to ensure reproducibility, allowing you to generate the same prompt multiple times if needed. This functionality is ideal for generating prompts for AI art generation, storytelling, or any other creative endeavor that requires varied text inputs.

Prompt from template 🪴 Input Parameters:

template

The template parameter is a string that contains the text template with placeholders that will be replaced by items from predefined lists. The placeholders are enclosed in square brackets, e.g., [list_name]. You can also specify the number of items to be replaced by using a comma, e.g., [list_name, 3]. This parameter supports multiline input and dynamic prompts, allowing for complex and varied prompt generation. The default value is an empty string.

seed

The seed parameter is an integer that sets the seed for the random number generator used in the prompt generation process. This ensures that the same template and seed will always produce the same prompt, providing reproducibility. The seed value can range from 0 to 0xFFFFFFFFFFFFFFFF, with a default value of 0.

Prompt from template 🪴 Output Parameters:

STRING

The output is a single string that contains the generated prompt with all placeholders replaced by items from the predefined lists. This string can be used directly as an input for other nodes or processes that require text prompts.

Prompt from template 🪴 Usage Tips:

• Use descriptive and meaningful list names in your template to make it easier to understand and manage.
• Experiment with different seed values to generate a variety of prompts from the same template.
• Combine multiple placeholders in a single template to create more complex and interesting prompts.
• Use the item_count feature to generate multiple items from a list, adding more diversity to your prompts.

Prompt from template 🪴 Common Errors and Solutions:

Cannot execute because a node is missing the class_type property.

• Explanation: This error occurs when a node in the prompt does not have the class_type property defined.
• Solution: Ensure that all nodes in your prompt have the class_type property correctly defined.

Cannot execute because node {class_type} does not exist.

• Explanation: This error occurs when the specified class_type does not exist in the NODE_CLASS_MAPPINGS.
• Solution: Verify that the class_type is correctly spelled and exists in the NODE_CLASS_MAPPINGS.

Prompt has no outputs

• Explanation: This error occurs when the prompt does not produce any outputs.
• Solution: Ensure that your template and seed values are correctly set and that the placeholders in the template match the available lists.
