Users often need to filter projects based on specific criteria. A common requirement is to allow users to search for urgent projects. However, filtering objects using boolean fields can present challenges, as demonstrated by a common error encountered during implementation. The Problem In the given scenario, a developer faced the issue of filtering a search bar for projects based on an urgent boolean field in their Project model. The model layout is as follows: [[See Video to Reveal this Text or Code Snippet]] The developer initially attempted to filter based on the urgent field using the query Q(urgent__icontains=q), which failed because icontains is not valid for boolean fields. Instead, they found that Q(urgent=q) worked initially, but later resulted in a ValidationError because the input was not strictly true or false, leading to the error: “” value must be either True or False. The Solution To implement a robust search functionality that includes filtering by boolean fields, follow these steps: Step 1: Define Helper Function to Validate Query Parameters In your views.py, create a helper function to confirm that query parameters are valid: [[See Video to Reveal this Text or Code Snippet]] Step 2: Update the Search Function Modify the search function to include filters for the complete and urgent boolean fields based on user input.
