I&#39;m trying to return an observable when I get a certain value in a subscriber, but I fail miserably. 

This is the code:

    canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):Observable&lt;boolean&gt; {
        // get route to be activated
        this.routeToActivate = route.routeConfig.path;

        // get user access levels        
        return this._firebase.isUserAdmin          &lt;-- returns Subscription, not Observable
            .map(user =&gt; user.access_level)
            .subscribe( access =&gt; {
               // I need to return an observable here
            });
    }

There are not many resources on observables in angular 2, so I don&#39;t know where to start. Can anyone help with this please?

**UPDATE -&gt; Working Version**

    canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):Observable&lt;boolean&gt; {
                // get route to be activated
                this.routeToActivate = route.routeConfig.path;
        
                // get user access levels        
                return this._firebase.isUserAdmin
                    .map(user =&gt; {
                        let accessLevel = user.access_level;
                        
                        if (accessLevel === &#39;admin&#39; ) {
                            return true;
                        }
        
                    }).first();
            }

How to return observable from subscribe

I found this solution. Is it valid?

    import {Component} from &#39;@angular/core&#39;;
    import {Platform} from &#39;ionic-angular&#39;;

    @Component({...})
    export MyApp {
    constructor(platform: Platform) {
      platform.ready().then((readySource) =&gt; {
        console.log(&#39;Width: &#39; + platform.width());
        console.log(&#39;Height: &#39; + platform.height());
      });
     }
    }

This solution is for ionic 2.
can i also used for angular 2?

Please suggest me the right way to do it.

I&#39;m using Docker to create a container to test my web app built on PHP and MySQL on my Mac.  My PHP app is built using Fat-Free Framework for MVC and routing.  I have two Dockerfiles, one for MySQL and one for PHP.  I&#39;ve used test Docker applications successfully, so I believe my images are installed correctly.

The main part of the error:

    Internal Server Error
    
    SQLSTATE[HY000] [2002] No such file or directory
    
    [fatfree/lib/DB/SQL.php:466] PDO-&gt;__construct(&#39;mysql:host=127.0.0.1;port=3306;dbname=robohome&#39;,&#39;root&#39;,&#39;password&#39;,array(1002=&gt;&#39;SET NAMES utf8;&#39;))

Note, if I connect using `127.0.0.1` instead of `localhost` I get a slightly different error that says: `SQLSTATE[HY000] [2002] Connection refused`

My PHP Dockerfile:

    FROM php:5.6-apache
    
    RUN docker-php-ext-install mysqli pdo pdo_mysql
    RUN a2enmod rewrite

My MySQL Dockerfile:

    FROM mysql:5.7
    
    ENV MYSQL_ROOT_PASSWORD password
    ENV MYSQL_DATABASE robohome
    
    COPY ./schema.sql /docker-entrypoint-initdb.d/

My `Controller.php` file where the error mentions line 24:

    &lt;?php
    
    namespace Controllers;
    
    class Controller
    {
        protected $f3;

        public function __construct()
        {
            $f3 = \Base::instance();
            $this-&gt;f3 = $f3;
    
            $mysqlServerName = $f3-&gt;get(&quot;MYSQL_SERVERNAME&quot;);
            $mysqlDatabseName = $f3-&gt;get(&quot;MYSQL_DBNAME&quot;);
    
            //$container = \DI\ContainerBuilder::buildDevContainer(); &lt;-Not used currently

                $f3-&gt;get(&quot;MYSQL_PASSWORD&quot;)
            );
    
            $this-&gt;db = $db;
        }

Those `MYSQL_*` values are pulled from an `.ini` file:

    MYSQL_SERVERNAME = &quot;localhost&quot; &lt;-This is what I&#39;ve tried changing to 127.0.0.1
    MYSQL_USERNAME = &quot;root&quot;
    MYSQL_PASSWORD = &quot;password&quot;
    MYSQL_DBNAME = &quot;robohome&quot;

My Docker compose file:

    version: &#39;2&#39;
    
    services:
      web:
        build: ./docker/php
        ports:

      db:
        build: ./docker/mysql
        ports:
          - 3306

I run this by doing `docker-compose up --build -d`.  The output I can then get from `docker ps` is:

From my research, I&#39;ve tried connecting using both `localhost` and `127.0.0.1` since they&#39;re technically treated differently.  It could also be something related to trying to talk via sockets instead of TCP.  Ideally I would like a solution that I can bake into my Dockerfiles so I don&#39;t have to worry about remembering commands or how I did something.

Using Docker I get the error: &quot;SQLSTATE[HY000] [2002] No such file or directory&quot;

I am getting an error:

&gt; Fatal error: Constant expression contains invalid operations in
&gt; config.php on line 214

That line was:

     protected static $dbname = &#39;mydb_&#39;.$appdata[&#39;id&#39;];

Whether I did any mistakes in quotes? Or somewhere else?

My search for the error message only showed a different source cause (a dynamic default value in a function definition).

How to open recently closed file in PhpStorm?

Unlike Netbeans, in Jetbrains IDEs, the setting files related to user and team are mixed in the same folder that makes it tricky when you need to push them to git. 

There is a number of sample git ignore files for these IDEs and https://intellij-support.jetbrains.com/hc/articles/206544839 page on git site. 

However, after using them for a months we figure out that it is safer and actually more convenient to do the reverse. I mean ignoring all `.idea` files and adding only team-related settings explicitly. (instead of adding all and ignoring some). 

The main thing that can be shared among developers is code style configs. So, by using IDE auto-reformatting option all the team will follow a consistent style. 

Besides that, the question is which other files are recommended to be included and not ignored? Why?

Answer: I came across with this: https://github.com/salarmehr/idea-gitignore

Which files in .idea folder should be tracked by Git?

I DON&#39;T care about looking at the git history of a file that has been marked as &quot;modified&quot;. 

What I want is something akin to what WebStorm/PhpStorm have where you can select any file in your project (modified or NOT) and inspect it&#39;s git history and all the changes to that file.

I also DON&#39;T want to have to look down the list of the git tree, and click on each one to see which files were commited.
