What

Sometimes admins want to make all selected investments's prices & explanations public at the same time, but without enabling the Final Voting phase, so there can be some feedback and corrections.

This PR allows admins to switch a Budget's phase from Valuating projects to a new phase Publishing projects prices (without having to change to Balloting projects) to make the prices & prices explanations public both on the Budget's investments list and on the investments detail page.

How

• Adding a new Budget phase publishing_prices 922318b & 6772f94

• Creating a published_prices? helper function at Budget model, as well as a phases constant to know which phases should have prices published 21d6ce5

• Refactoring existing should_show_price? and should_show_price_info? Budget's helper functions to reflect new logic 3340917

Screenshots

A gif is worth a thousand screenshots

1. We check that a selected investment with price & price explanation, on a Budget at "Valuating projects" phase doesn't show them neither on list or detail

2. We check that changing Budget's phase to "Publishing project prices" both price & price explanation are shown on both list and detail
   

Test

• Added investment feature specs to check price showing rules 1d6c303
• Increased Budget model specs cb1151f
• Increased Investment model specs 3563b87
• Removed a test scenario that was deprecated with the new showing logic f350b99

Deployment

As usual

Warnings

Some small refactors on the side to make changes easier and code more clean:
