0:01 All right, we have our first Eve application up and running
0:04 let's review what we've done so far.
0:06 Our app is made of two Python scripts,
0:09 one is app and the other one is settings.
0:12 What is perhaps more interesting is that the actual app is
0:17 00:16.96 only made of one line of actual code,
0:19 and the second script is more a configuration file
0:22 than a real Python scrape,
0:25 and this is probably the basic concept behind any Eve application.
0:29 which is that most of the heavy-lifting is done by the framework itself
0:33 you mostly have to just configure how it should behave
0:37 according to your use case.
0:42 On the first line, we're connecting to our db,
0:44 in this case, we're connecting to a local instance,
0:48 but it could very well be some remote instance,
0:51 maybe a replica set hosted on, I don't know,
0:53 Mongo address service or whatever have you.
0:57 Next, we set the methods allowed
1:02 at both the collection and document endpoint
1:05 by default, Eve is read only, so if you want to allow for clients
1:11 to write or edit or delete, you have to explicitly say so
1:16 by extending these lists here.
1:20 Next, we defined the API surface or as they call it,
1:25 the domain of our API,
1:27 here we defined one single endpoint,
1:31 the schema for this endpoint, is defined in people schema over here.
1:37 We only have two fields and they're both of type string,
1:41 by the way, here we are justifying the type of the field
1:44 but in fact, there are a lot more options
1:48 we will have a specific lecture about data validation
1:52 and we will see how many options we have
1:55 when we want to make sure that the data coming in
1:58 is a properly formatted and validated.
2:01 Now, you might be wondering
2:03 what if I want some endpoints to be read only,
2:06 others may be to be write only,
2:08 and all the rest be read and write?
2:11 We only set the globals here but we can go and overwrite the globals
2:16 when we define every single endpoint,
2:19 for example, let's say that we have a second endpoint works
2:22 and here we want to be read only,
2:25 well, all we have to do is overwrite the global setting
2:29 resource, methods,
2:32 and then probably we also want to be with read only at the item endpoint
2:44 and that's it, by the way notice how here we're using the lower cases
2:48 while in the global settings, we use the upper case.
2:52 So, people is going to use the global setting
2:56 because it is not redefining the rules,
2:59 works is going to be read only
3:01 because of these two declarations here overwriting the global.
3:05 Okay, I believe we're done with the first app,
3:09 just keep in mind that because most of the heavy lifting is done by the framework,
3:13 and yes, it is a strongly opinionated framework,
3:16 most of the features we saw in the quick tour a few lectures ago,
3:21 they're already available to your app,
3:23 even if it is a simple one like this one.
3:26 For example, we could go back to our postman client
3:29 and perform queries sorting,
3:31 ask for xml rendering— let's do that, just for fun.
3:36 Let's, go here, do a get to our document endpoint
3:41 and lets ask for xml. Here we go.
