PANTS TODOs and Roadmap

(including known bugs/issues/kludges)

Urgent / Important

  • ** Unit tests are severely incomplete! **
  • In particular need coverage to catch keyerrors on new installs, and other things that are going to affect new users.
  • Fix all the FIXMEs in the code (see "make fixme" output) (most of these now relate to the NData work)

API v1 (In Progress)

  • GET/POST/PUT/DELETE for DiaryFood [done]
  • Model-level permissions for API views [done]
  • Per-user ing/rec data (Nullable user field; exclude if user!= request.user) [done]
  • GET/POST/PUT/DELETE for Ingredient [done]
  • GET/POST/PUT/DELETE for Recipe [done]
  • Add nested tags/flag/etc to Ingredient/Recipe serialisations [done]
  • Add recipe component GET, POST/PUT/DELETE for user-owned Recipe [done but writing won't work without below]
  • Add create() so component can be saved with Recipe in the one call [in progress]
  • GET all IngredientTag/RecipeTag/Flag for display
  • Document API action to get recent (last 2 days) diary data via django-filter instead of custom view
  • Add custom API response to get diary aggregate data (get_diary_aggs() calls) - note home page uses this but not above call for full details
  • Add price GET, POST/PUT/DELETE - user Ingredients only, or own prices on global ingredients?, supplier stringfield
  • Check object-level permission to ensure users can only change their own objects (not global ones)
  • Add auth methods suitable for HTTP servers and/or native/desktop/app clients
  • Document Django user permissions required to allow users to add/edit/delete DB objects

NData and calculation DRYing (should be done before further recipe/diary work)

All the nutrition_data properties should be its own class that manages access/validation/caching/etc, and does operations like summing and averaging. This will remove LOTS of almost-identical code across ingredient/recipe/diary.

  • ndata class/mixin
  • ndata mixin for ing
  • ndata mixin for rec
  • ndata mixin for diary
  • Fix per-serve/per-weight dichotomy in recipe components [done]
  • Merge recipe and ingredient handling in diary save() and elsewhere
  • Use F()/aggregate/annotate expressions in recipe calcs
  • Allow filtering on calculated ndata
  • Remove NDATA_ settings cruft
  • ndata should handle micronutrients in some generic and graceful way

Deploy and Login, Production-Readiness

  • Provide a fixture with some initial basic ingredients [done]
  • Provide a fixture with few initial basic recipes, including at least one meta
  • All urgent/important stuff at top done
  • Deploy target assuming Heroku - include sub-parts below
  • Proper non-admin login/logout pages [done by AustinGrey]
  • Use login middleware instead of requiring mixins/decorators every view
  • 404 template

Filtering Options

  • Use django-filter (replace custom tag view handling etc) (work in progress, mostly done)
  • Limits and other context in FilterView
  • Allow filtering on calculated ndata
  • Fix/style form in ing-filter template
  • filter recipe, diary as for ings

Exercise and Physiological Diary

  • Exercise diary item (start/stop time, calories, distance, etc)
  • Physiological data diary item (weight, resting pulse, peak breath flow, body tape measurements, body fat caliper measurements, blood sugar etc)
  • Show above in same table (3 rows of headers for item types)
  • Derived physio data (BMR, body fat % from multiple sources, lean mass...)
  • Deltas of physio data (weight loss, body fat % loss, lean mass gain etc)
  • Totals and other aggregates for exercise/physio data

User Profiles

  • User-prof-object to hold age, height etc (age required for some physiological calcs)
  • User preferences for FE (e.g. KJ or calories display, don't show some columns)
  • Custom user "rank" formula replacing the built in hardcoded sorting rank
  • Fix setting of daily target on target list page

Django Frontend

  • Automatic conversion of kilocalories to kilojoules when entering ingredients
  • Allow entering ingredients per-100g or per-arbitary-grams
  • Ratio bar charts on ingredient detail aren't very useful without the ability to scale by grams or servings
  • Ratio bar charts on recipe detail use only max limit; should use midpoint of min/max
  • Replace recipe/ and ingredient/ with "landing" page with a list of tags and count of ings for each etc, links to /all/ etc
  • Diary entry admin page should default to logged in user, etc
  • Clean up templates by using more templatetags
  • Handle particular target values set as None gracefully where they are displayed in lists
  • 3-part bar chart templatetag for max-min-current target comparison
  • Sanity Check page also listing out of date (e.g. nutrition over 2 year (?), price over 6 months)
  • Add chosen target comparison on recipe/ingredient detail pages (for pre/post workout targets etc)
  • Consider Daily target comparison as an option on recipe/ingredient list pages
  • "tags:" text should be a button that toggles tag-bar visibility on/off
  • Diary edit/create/delete forms using generic views too
  • Ing list column with recipe count (recursive/nonrecursive), click for recipe list filtered to ing?
  • Bottom nav buttons for convenience
  • View-on-site in all admin

Miscellaneous

  • Add Wall/Prep/Cooking times to recipes
  • Add the capacity for recipes to lose water/oil during the process (changing the nutritional output to not be just the sum of ingredients)
  • Add preparation_loss_factor to Product for e.g. peeling and trimming losses (can be half quantity for some vegetables, making them less cost-effective; also required for shopping list quantities etc). Add on product to allow e.g. pre-chopped vs whole veg price comparison
  • Bug: Does not detect recursion loops in recipes
  • Bug: User must handle out of date slugs on a name change
  • Copy some of the cleaner explanations of the ratios and meta-recipes from various blog posts to README (also, clean up README in general)
  • Diary doesn't rewrite cost if there is no cost on ingredient/recipe - should be allowed as a manual override but at least give a warning.
  • Improved bulk import facilities in general, especially open data
  • "Favourite" ings/recs - show first in add-diary-item etc
  • Diary nav for historic data - ArchiveView / TodayArchiveView/ DayArchiveView ?
  • Recipe is_vegan/is_vegetarian/gluten_free/has_gluten properties - check via ingredient tags
  • Invalidate cache of ingredient/recipe/quantity on nutrients change
  • Invalidate cache of product/ingredient/etc on price change
  • Option to Flatten and/or Crystallize ingredients on recipe detail view? Alternatively a "Print" version
