* ForeignKey.swappable

* REST PERMISSIONS

* Databases.User add reverse M2M databases widget (like mailbox.addresses)

* Make one dedicated CGI user for each account only for CGI execution (fpm/fcgid). Different from the files owner, and without W permissions, so attackers can not inject backdors and malware.

------------

* Generate a password-less ssh key, and copy it to the servers you want to orchestrate.
ssh-keygen
ssh-copy-id root@<server-address>

Php binaries should have this format: /usr/bin/php5.2-cgi


* logs on panel/logs/ ? mkdir ~webapps, backend post save signal? 
* <IfModule security2_module> and other IfModule on backend SecRule

# Orchestra global search box on the page head, based https://github.com/django/django/blob/master/django/contrib/admin/options.py#L866 and iterating over all registered services and inspectin its admin.search_fields

* contain error on plugin missing key (plugin dissabled): NOP, fail hard is better than silently, perhaps fail at starttime? apploading machinary

* contact.alternative_phone on a phone.tooltip, email:to

* make sure that you understand the risks

* full support for deactivation of services/accounts
    * Display admin.is_active (disabled account special icon and order by support)

* lock resource monitoring
* -EXecCGI in common CMS upload locations /wp-upload/upload/uploads
* cgi user / pervent shell access

* prevent stderr when users exists on backend i.e. mysql user create

* disable anonymized list options (mailman)

* tags = GenericRelation(TaggedItem, related_query_name='bookmarks')

* user provided crons

* ```<?php
$moodle_host = $SERVER[‘HTTP_HOST’];
require_once(‘/etc/moodles/’.$moodle_host.‘config.php’);``` moodle/drupla/php-list multi-tenancy

* make account available on all admin forms

* more robust backend error handling, continue executing but exit code > 0 if failure: failing_cmd || exit_code=1 and don't forget to call super.commit()!!

* website directives uniquenes validation on serializers

+ is_Active custom filter with support for instance.account.is_Active annotate with F() needed (django 1.8)

* document service help things: discount/refound/compensation effect and metric table
* Document metric interpretation help_text
* document plugin serialization, data_serializer?
* Document strong input validation

# bill line managemente, remove, undo (only when possible), move, copy, paste
    * budgets: no undo feature

* Autocomplete admin fields like <site_name>.phplist... with js

* allow empty metric pack for default rates? changes on rating algo

* payment methods icons
* use server.name | server.address on python backends, like gitlab instead of settings?

* TODO raise404, here and everywhere
* update service orders on a celery task? because it take alot

# FIXME do more test, make sure billed until doesn't get uodated whhen services are billed with les metric, and don't upgrade billed_until when undoing under this circumstances
#    * line 513: change threshold and one time service metric change should update last value if not billed, only record for recurring invoicing. postpay services should store the last metric for pricing period.

* move normurlpath to orchestra.utils from websites.utils

* write down insights

* websites directives get_location() and use it on last change view validation stage to compare with contents.location and also on the backend ?

* modeladmin Default filter + search isn't working, prepend filter when searching

* create service help templates based on urlqwargs with the most basic services.

autocomplete; on the form header and type="search"
To latest developers to post on this thread: I implemented the workaround I described in comment #14 nearly three months ago, and it has worked perfectly since then. While we would all prefer that "autocomplete=off" function properly at all times, it still functions properly if you include in your form an input element with any other autocomplete value.

I simply added this code to my layout:

<div style="display: none;">
 <input type="text" id="PreventChromeAutocomplete" name="PreventChromeAutocomplete" autocomplete="address-level4" />
</div>

Once I did this, all of my "autocomplete=off" elements were respected by Chrome.
<input type="password" name="password" value="" style="display: none" />

### Quick start
    0. Install orchestra following any of these methods:
        1. [PIP-only, Fast deployment setup (demo)](README.md#fast-deployment-setup)
        2. [Docker container (development)](INSTALLDEV.md)
        3. [Install on current system (production)](INSTALL.md)
    1. Add the servers that you want to manage on `/admin/orchestration/servers` and copy orchestra's SSH pubkey to them
        `orchestra@panel:~ ssh-copy-id root@server.address`
    2. Now configure service by service (domains, databases, webapps, websites...):
        1. Add the route through `/admin/orchestration/route/`
        2. Check and configure related settings on `/admin/settings/setting/`
        3. Configure related resources if needed `/resources/resource/`, like Account Disc limit and traffic.
        3. Test that everything works by creating and deleting services
        4. Do the same for the other services
    3. Configure billing by adding services `/admin/services/service/add/` and plans `/admin/plans/plan/`
        1. Once a service is created hit the *Update orders* button


### Architecture
    Orchestration
    Orders


### Creating new services
    1. Think about if the service can fit into one of the existing models like: SaaS or WebApps, refere to the related documentation if that is the case.
    2. Create a new django app using startapp management command. For ilustrational purposes we will create a crontab services that will allow orchestra to manage user-based crontabs.
        `python3 manage.py startapp crontabs`
    3. Add the new *crontabs* app to the `INSTALLED_APPS` in your project's `settings.py`
    3. Create a `models.py` file with the data your service needs to keep in order to be managed by orchestra
    ```python
from django.db import models

class CrontabSchedule(models.Model):
    account = models.ForeignKey('accounts.Account', verbose_name=_("account"))
    minute = models.CharField(_("minute"), max_length=64, default='*')
    hour = models.CharField(_("hour"), max_length=64, default='*')
    day_of_week = models.CharField(_("day of week"), max_length=64, default='*')
    day_of_month = models.CharField(_("day of month"), max_length=64, default='*')
    month_of_year = models.CharField(_("month of year"), max_length=64, default='*')

    class Meta:
        ordering = ('month_of_year', 'day_of_month', 'day_of_week', 'hour', 'minute')

    def __str__(self):
        rfield = lambda f: f and str(f).replace(' ', '') or '*'
        return "{0} {1} {2} {3} {4} (m/h/d/dM/MY)".format(
            rfield(self.minute), rfield(self.hour), rfield(self.day_of_week),
            rfield(self.day_of_month), rfield(self.month_of_year),
        )

class Crontab(models.Model):
    account = models.ForeignKey('accounts.Account', verbose_name=_("account"))
    schedule = models.ForeignKey(CrontabSchedule, verbose_name=_("schedule"))
    description = models.CharField(_("description"), max_length=256, blank=True)
    command = models.TextField(_("content"))

    def __str__(self):
        return (self.description or self.command)[:32]
```
    
    4. Create a `admin.py` to enable the admin interface
        ```python
        from django.contrib import admin
        from .models import CrontabSchedule, Crontab

        class CrontabScheduleAdmin(admin.ModelAdmin):
            pass

        class CrontabAdmin(admin.ModelAdmin):
            pass

        admin.site.register(CrontabSchedule, CrontabScheduleAdmin)
        admin.site.register(Crontab, CrontabAdmin)
    
    
    5. Create a `api.py` to enable the REST API.
    6. Create a `backends.py` fiel with the needed backends for service orchestration and monitoring
        ```python
        import os
        import textwrap
        from django.utils.translation import ugettext_lazy as _
        from orchestra.contrib.orchestration import ServiceController, replace
        from orchestra.contrib.resources import ServiceMonitor

        class UNIXCronBackend(ServiceController):
            """
            Basic UNIX cron support.
            """
            verbose_name = _("UNIX cron")
            model = 'crons.CronTab'
            
            def prepare(self):
                super(UNIXCronBackend, self).prepare()
                self.accounts = set()
            
            def save(self, crontab):
                self.accounts.add(crontab.account)
            
            def delete(self, crontab):
                self.accounts.add(crontab.account)
            
            def commit(self):
                for account in self.accounts:
                    crontab = None
                    self.append("echo '' > %(crontab_path)s" % context)
                    chown
                    for crontab in account.crontabs.all():
                        self.append("
        #            if crontab is None:
        #                self.append("rm -f %(crontab_path)s" % context)
        ```
    7. Configure the routing
