Create Bat model

[mcab]

Addresses #4.

By utilizing some of PostgreSQL's special fields, we can reduce the amount of columns we would need to use for specific fields.

Things that we can keep track of:

• Common name
• Scientific name
• Rarity of bat (common, seasonally common, rare)
• Habitat patterns (hibernates, migrates, cave roots, tree roosts)
• Size (how big in units)
• Pups (how many pups are born per year)
• Risk (not threatened, endangered, threatened, special concern)
• Risk scope (if it's affected at the federal or state level)
• Image (what the bat looks like)

Things that aren't fully working:

• Bat admin page needs a bit of a tune up.
  • Each field needs help text to describe what it does
  • Habits needs to be renamed to Habitat Patterns
  • Habitat patterns Habits need to have a way to select multiple items and not the short-hand code for it (HI, MI, etc.)
  • Size needs to go in smaller increments (.1)
  • Size requires a text field for units
  • Risk and Risk scope needs to be changed from ArrayField to just CharField, or have a way to tie each Risk scope to a particular risk
  • Bat Image needs to be editable from that screen.

Good news is that we have Bats listed in the admin menu now!

We also can see the overview of all the Bats, but we might need to think of a better way to search / view them.

Made the edit page a bit less long. Still need to address the range fields (for size and pups).

• Added help text for each field (hard-coded per model seems wrong, but I don't see a better solution, unless we use a snippet for each help_text or something. That's overkill.)
• Added better selector for habits / risk / risk scope

Decided that a risk per risk scope would require a bit more robust selection + modeling, and probably out of scope for now.

Habits was actually right. I don't know what I said when thinking it should be "habitat patterns."

Size is tricky. I think at this stage, we need to create another widget to allow for a specific step to be inserted, or some other solution.

Might be a silly question, but I got error when trying to load this page on my end

what's the url for accessing this site?
