Summary

Addressed following problems:

  • UI form elements in the quick logging did not match the elements in full log form. (Whole app seems to have elements mismatching)
  • UX when filling in the "quick" form was exceptionally frustrating, chasing input recalculations.

Changelog

  • Added: Prepopulate the last fuel price in quick form.
  • Changed: Aligned UI element in quick from with what full form has.
  • Fixed: Only allow value recalculation on opposite values in quick form, while fuel price remains a manually input value unless already populated by previous value.

Testing

How were these changes tested?

  • Tested locally
  • Tested with Docker image

Summary by CodeRabbit

  • New Features

    • The quick fuel entry form now shows the most recent recorded price per unit for each vehicle.
    • Switching vehicles updates the displayed price automatically.
  • Improvements

    • Updated form fields with a cleaner, more consistent visual style and improved focus states.
    • Streamlined quick fuel calculations when entering total cost and volume.
    • Preserved recorded zero prices instead of treating them as blank.
    • Simplified the “Save & Add Another” button styling.

📝 Walkthrough

Walkthrough

The quick fuel route now resolves accessible vehicles and retrieves vehicle-specific fuel prices. The form pre-fills the selected price, preserves zero values, updates calculations when the vehicle changes, and uses revised input styling. Tests cover route, browser, and station-history behaviour.

Changes

Quick fuel form

Layer / File(s) Summary
Resolve and render vehicle fuel prices
app/routes/fuel.py, app/templates/fuel/quick.html, tests/test_quick_fuel_prices.py
The route selects an accessible vehicle, filters prices by effective fuel type and valid range, and passes prices for all vehicles. The template preserves zero prices and pre-fills the selected price. Tests cover vehicle, user, fuel type, and missing-price cases.
Update form behaviour and presentation
app/templates/fuel/quick.html
The form controls use revised classes. Vehicle changes update the price field and total. Calculation branches accept zero prices and update total-based volume calculations.
Validate price and calculation paths
scripts/check-quick-fuel.cjs, tests/test_quick_fuel_prices.py
The checks exercise vehicle price switching, zero and empty prices, calculation branches, and zero-price station history recording.

Merge Risk: ⚪ Minimal · up to 7aece

Zero-price quick fuel entries now retain a zero total and station-price history, so the previously identified submission issue no longer blocks merging.

unchanged.

521-521: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Use null-aware checks for zero prices and costs.

parse_decimal('0') returns numeric zero, and FuelLog accepts it. The truthiness checks at app/routes/fuel.py:521-524 therefore skip derivation and save total_cost=None. The check at app/routes/fuel.py:558 also skips FuelPriceHistory creation and station.increment_usage().

Use is None and is not None for optional numeric fields. Keep the non-zero volume guard before division. Add POST coverage for zero-price derivation and station history.

the earlier zero price so the upper-bound price_per_unit filter is covered.
