I'd like some advice about compojure-api. I began with a routes list like this:

(context* "/api" []
  (context* "/users" []
    <many routes>)
  (context* "/videos" []
    <many routes>))

(context* "/api" []
  users-context
  videos-context)

@amacdougall instead of def + context*, try defroutes*. plan in to move swagger-doc generation from compile time to runtime soon, so the the def + context* would work too. There is a #C06GSN6R2 if you'd like to chat more. cheers.

@sveri: thanks, im just awake and will look into it

@sveri: looks nice, if I only want to use selmer and the login , autherisation part without reagent. Do I have to use only the clj directory in src ?

sorry for so many questions but im eager to learn

@roelof yes, the backend stuff is in clj folder and the templates are in resources/templates

oke, thanks, I will play today with it

@sveri if I want to start clean I can do lein new compojure app-name

Yes, that is one way to do it

oke, and the other is ?

Starting with an empty leiningen template or adapting an existing one like closp or luminus

No matter which route you take, understanding all the moving parts will take months

that is no problem

As I said yesterday this is a hobby project of mine

I like to closp one but then I have to delete a whole part

I still have to learn things like cljs , figwheel and so on

So I will start with just clojure , my first goal is to set up the login part and the templates

then maybe it's best to start with compojure

and add the libraries step by step by following the documentation on their page

However, there is one thing that will speed up development much more, especially when learning things

By using component or mount you will be able to reload code without restarting the repl everytime

this is especially useful to find compile errors as a reload will show them

and after you fixed the error you can just reload again and see if it works

oke, thanks

I wil dive in component first

you might as well take a look at mount:https://github.com/tolitius/mount might be easier to get

Thanks, looks difficult

of course this is always subjective, but getting component to work was one of the hardest parts of all for me starting with clj / cljs and compared to that mount looks easier to understand, but, like I siad, that's just my point of view

component is very un-lispy compared to mount

with mount you just have a var in a namespace

maybe I ask for help if im ready to use databases and sessions

and will study the closp source code well

First task : settting up the project and translate the layout to selmer

I have this :

` (ns clcommerce.routes.home
(:require [compojure.core :refer [defroutes GET]]
          [clcommerce.layout :as layout]
          [ring.util.response :refer [response]]))

(defn home-page []
  (layout/render "home/index.html"))

(defn contact-page []
  (layout/render "home/contact.html"))

(defroutes home-routes
           (GET "/" [] (home-page))
           (GET "/contact" [] (contact-page)))

but now I see this error message : No such var: layout/render

what do I miss in the require part

The require looks fine to me. If it was wrong, I would expect you to get an error there or something like “No such namespace: layout”. What does clcommerce.layout look like. Are you sure there’s a render in it? Or maybe you haven’t loaded the latest changes in that file?

@solicode: you mean the layout.clj file

Yeah

That one has this into it :

(ns clcommerce.layout
  (:require [selmer.parser :as parser]
    )
)

(parser/set-resource-path!  ( "templates")) 

so no render function

Okay, yeah, that’s the problem

Where can I find a good example of a render function for selmer templates ?

Selmer seems to have its own render function. So I’m not sure if you would need to define your own like this in layout. Can’t you use Selmer’s render directly?

I think I can . So I have to change layout/render to render ??

I do not use cljs or reagent so I think it can work

Im a beginner in this

There's an example here: https://github.com/yogthos/Selmer#templates So Selmer has a render-file function which seems to be the one you want.

So you can require selmer and use that function directly.

oke, I will experiment with it but still adding (ns clcommerce.layout (:require [selmer.parser :as parser] does not solve it. Still render-file cannot be resolved

Are you calling it with parser/render-file?

nope, only render-file

oke parser/render-file does it

Right, that’s what :as parser is doing. You can call it whatever you want.

now trying to find out why (parser/render-file "home/base.html")) gives a wrong arity

In the example, it shows you can pass variables to the template. So it looks like it’s not overloaded. You can pass an empty map to it.

(parser/render-file "home/base.html" {})

Eventually, I’m assuming you’ll put stuff in that map, like: (parser/render-file "home/base.html" {:name "Whatever”})

Then in your template, I think you can do {{name}} and use it.

I’m not too familiar with Selmer, but it seems like that’s how you use it.

Thanks

I found that out already

yes, my first template is running

it costs me the whole morning but it works

now next problem : find out how I can tell the css files are in the resources directory

also solved

now I can work on the rest of the template

@solicode: thanks for the help

@roelof: No problem

Does the end of Prismatic also mean a big change in Prismatic/Schema being maintained?

@borkdude: maybe a stupid question but what does Prismatic/Schema exactly do ?

@roelof: check it out here. basically structural validation: https://github.com/Prismatic/schema

oke, can I also use it for input validation ?

@roelof: sure

oke, maybe a good one to keep a eye on for form validation for my hobby-project

What is the right way to make a java script tag working with Selmer

@martintrojer: Hi, since joplin 0.3 do I understand it correct that I have to define some code to execute migrations? Up to 0.3 I could just define some configuration and then run the migration with the leiningen plugin without one line of clojure code. Is that still possible?

The very least you have to do is to define aliases I think - https://github.com/juxt/joplin/blob/master/example/project.clj#L14-L19

@sveri if you want to run migration / seeds from the command-line you need to implement the aliases

I tend to only use the ‘joplin repl’ nowadays

@martintrojer: I already commented in one of the issues, pre 0.3 it was possible to run a migration without a line of clj code only by configuration.Now I have to write some helper code. Is there a reason to do it like this?

yeah, lein plugins are no good. But like you said in GH#71 some of the boiler plate could be moved into core

PR welcome

I am curious, why you think that lein plugins are no good? Because they are coupling leiningen to your project?

Since joplin potentially brings loads of dependencies, I had various hacks in the plugin only to require the databases you were using.

Also, I really wanted to move the config out of project.clj

I looked a few minutes into the code and my first understanding of joplin.repl/migrate was that the conf param takes a filename where the configuration resides in the classpath. Later I realized it expects the config map. Would it be ok to accept both? the config map or a filename where the config is inside?

Then I won't need to write some code cause I could just provide the configuration

*The configuration file I mean

joplin.repl/load-config

its the edn reader with support for the tagged literals

The problem with taking the filename is that I want you to control where its coming from, resources / file-path etc

Hm and the problem with this approach is, I have to write clojure code to do migration

Yeah, but if we write a helper that take the filename, next week there will be a GH issue that somebody wants to load it from resources rather than filesystem path.

And what if we make it like this that the migrate functions calls load-config if conf is a filename or just executes the existing code if it is a map?

This way we would use the existing load-config function

so repl/load-config doesn’t take a filename either.

https://github.com/juxt/joplin/blob/master/example/src/alias.clj#L5

Ok, then I misunderstood the code

I dont understad that part: https://github.com/juxt/joplin/blob/master/example/src/alias.clj#L9 Why do you add some extra config into the existing one? Is this just an example? Or required everytime?

Yeah, only for this particular example

Ok, would you consider a PR where I just grab that example alias.clj and change the functions to parameterize "joplin.edn"?

and place that alias.clj besides repl.clj?

yes

I’m here to please

😄 thanks for the work btw.

Let's see if I get ready before my family calls. They are still working on the christmas cookies^^

figwheel provides a webserver when you don’t have one, but now I need one, because I want to serve many URLs. What’s the best way to add one that plays nicely with figwheel? Is it possible to not have to run both figwheel and the web server at the same time?

@martintrojer: Hm, I wanted to test the alias namespace and ran this snippet in a repl where I installed joplin.core and joplin.jdbc 0.3.5-Snapshot

Any idea whats going on here? the "here!!!" part is just a test println from me

oo joplin looks like something i'll want to use soon

@martintrojer: I have the same problem when I try to add the alias.clj to my project using joplin 0.3.4

Hm, could it be that my config is broken?

@martintrojer: Ok, it's a ragtime problem only occurring in windows due to the fileseparator

-.-

any Selmer users here. How do I use the javascript tag and the image tag in Selmer

and the meta tag

@martintrojer: I opened this issue: https://github.com/weavejester/ragtime/issues/91 for it. Will have to wait until this is fix so I can try out my PR

@sveri: do you use meta, javascript and /or images in your closp template ?

@roelof: I do sparingly, I think, but never took much care of them, as they are project specific in my opinion

oke, I try to convert a template where a lot of javascript , meta and javascript is used

I try to convert this ; https://laboutique.lemonstand.com/ with selmer

but on these tags I cannot find how I can do that in a template

but im going to sleep early so I will read your answer tomorrow if you give a answer

Hey!… I am having a hard time trying to understand how to apply coercion on one of my REST API end point. What I want is to coerce some query parameters based on a schema definition. For example, if I receive a request with some query parameters like “…/foo?status=0&name=“rcanepa”, I would like to transform the status value to an integer and pass to my handler a map like {“status” 0 “name” “rcanepa”}.

I forgot to say that I am working with compojure-api.

I think that I have to pass my schema in the :query-params keyword of the endpoint.

However, I am not sure how can I pass this “coerced” map to the handler.

The objective behind all of this, is to provide filtering, pagination and sorting features, so the query params may vary.

Now, I am doing this:

In that snippet, parse-contact-search-request is a def that calls coercer/coercer.

If test it, I will get an error for trying to pass a string as the value of the status keyword.

In summary, 1) coercion is not working, and 2) I don’t know how to correctly specify the schema for the :query-params on the endpoint.

@rcanepa: try either: :query-params [status :- s/Int name s/Str], binds status and name for the body.

@rcanepa: or if you want the whole map: :query [params {:status s/Int, :name s/Str}]; binds params for the body.

:query-params uses the Plumbing letk-syntax, :query works like a normal let.

Mmm… If I understood correctly, I could use something like

:query [params MySchema]

Yes, I can

@roelof: I am not sure what exactly your question is?
