• List the posts on the index page
• Have the navbar and sidebar on the main page.

Create a Post model with the following attributes:

• title: This field indicates the title of the idea post for a blog and should not be NULL.
• description: This field indicates the content of the post. It should not be NULL.
• upvotes: This integer field indicates the number of upvotes for the post. It should have a default value of zero and should not be NULL.
• downvotes: This integer field indicates the number of downvotes for the post. It should have a default value of zero and should not be NULL.
• is_blog_worthy: This boolean field indicates whether the idea can be transformed into a blog. It should have a default value of false.

Add the following validations to the Post model:

• Validate the presence of the title field. Also, make sure that it has a maximum length of 125 characters.
• Add custom validation to ensure that the net vote, i.e., upvotes - downvotes, does not acquire a negative value.
• Validate the presence of the is_blog_worthy field. If you want to validate the presence of a boolean field, you will want to use validates_inclusion_of :field_name, in: [true, false]
