Domain Practice lv1

In this DQ you'll practice drawing your ERD diagram to plan out your models and methods. If you are thorough in drawing this out, writing a lot of your code will be very straightforward, so try to be detailed through each piece of this DQ.

Think of this a little like a scavenger hunt. You'll start here, in the README.md. After you finish each set of "clues", they'll direct you to a different file where you can check your work before moving on to the next set.

Your Models

You will have three classes: Animal, Plant and AnimalToxin. AnimalToxin belongs to Animal and to Plant. Plant has many AnimalToxin. Animal has many AnimalToxin.

Animals will have a species (string), domesticated (boolean) and diet (string). All attributes will be readable. Only domesticated and diet can be changed.

Plant will have a common_name (string), a scientific_name (string), and a color (string). All attributes will be readable. Only common_name and color can be changed.

AnimalToxin will have a plant (Plant instance), animal (Animal instance) and a severity (integer). All attribute will be readable and can be changed.

Your Instructions

Draw the ERD Diagram... try to be as thorough as possible. You can use https://awwapp.com/, Google Drawing, or any other tool you can screenshare with your group.

Make sure that you include...

• Arrows for associations between models
• Instance and class variables denoted correctly
• What arguments should be included in the initialize method?
• What readers and writers should there be?
• What object association methods would you need to write? Do not write them yet; just write down which you'll need.

Next Steps

Now to DiagramPlan.md. In this file you'll see one way you could have drawn this out. Check against what your group drew; where there elements in the solution you didnt cover? Anything that is unclear?
