小编Pav*_*lli的帖子

我梳理了一下:http://www.postgresql.org/docs/current/interactive/app-psql.html#APP-PSQL-META-COMMANDSf和https://www.digitalocean.com/community/articles/how- to-use-roles-and-manage-grant-permissions-in-postgresql-on-a-vps-2但仍然无法使其工作.

我这样做是为了让postgres在本地工作:https://askubuntu.com/questions/42013/problem-installing-and-configuring-postgresql.

pavan@myUbuntuLaptop% which psql
/usr/bin/psql

这让我进入:

pavan@myUbuntuLaptop% sudo su - postgres
[sudo] password for pavan: 
postgres@myUbuntuLaptop% 

所以...

postgres@myUbuntuLaptop% createuser pavankat
Shall the new role be a superuser? (y/n) y
postgres@myUbuntuLaptop% 

这得到了所有的角色

\du

这显示了pavankat,所以角色已经完成

这有效:

postgres=# CREATE database lateraldev;
CREATE DATABASE
postgres=# \l

现在我尝试向用户授予lateraldev权限,pavankat:

这不起作用:

GRANT RULE ON lateraldev to pavankat

不起作用:

GRANT ALL ON lateraldev TO pavankat;

不起作用:

postgres=# GRANT ALL ON lateraldev TO pavankat;
ERROR:  relation "lateraldev" …

因此导轨不会与导轨生成一起工作.我认为问题是heroku toolbelt,所以我删除了它,但是没有做到这一点.然后我检查了我的.zshrc文件,看到它有一个不同版本的ruby,它在PATH中调用,所以我更新了.然而,这没有做到.我没有想法.有人可以帮帮忙吗？

一切都在这里工作.唯一的问题是,在我的手柄文件中,我必须得到一个人的任务,如下所示:

this.Tasks

我宁愿让它看起来像这样:

this.tasks

我如何定制Sequelize呢？

这就是我的应用程序的根路径(它呈现index.handlebars文件)

我的路线:

router.get('/', function(req, res) {
  models.Person.findAll({
    include: [ models.Task ]
  }).then(function(people) {
    res.render('index', {
      user_id: req.session.user_id,
      email: req.session.user_email,
      logged_in: req.session.logged_in,
      people: people
    });
  });
});

我的index.handlebars文件:

  {{#each people}}
    <li>
      {{this.name}}
      {{#if ../logged_in}}
        <a href="/people/{{this.id}}/destroy"> destroy</a>
      {{/if}}
      <ul>
        {{#if ../logged_in}}
          <li>
            <form action="/people/{{this.id}}/tasks/create" method="POST" style="display: inline">
              <input type="text" name="task" placeholder="add task here">
              <input type="submit" value"assign task">
            </form>
          </li>
        {{/if}}

        {{#each this.Tasks }}
          <li>
            {{this.task}}
            {{#if ../../logged_in}}
              <a href="/people/{{this.person_id}}/tasks/{{this.id}}/destroy">destroy</a>
            {{/if}}
          </li>
        {{/each}}
      </ul>
    </li>
  {{/each}}

我安装了git,并设置了ssh密钥,但是我遇到了这个奇怪的错误.

我运行rspec时不断收到此错误:序列未注册:电子邮件.

但是,我确实在我的factories.rb文件中设置了它.有想法该怎么解决这个吗？该应用程序运行正常.

我一直收到这个错误:

您的SQL语法有错误; 检查与您的MySQL服务器版本对应的手册,以便在第1行的"食物"附近使用正确的语法ORDER BY'id''

我如何解决它？

<?php
require '113-connect-db.php';  
$query = "SELECT * FROM 'food' ORDER BY 'id'";

if ($query_run = mysql_query($query)){
echo 'query successful';

} else {
echo mysql_error();
}
?>

正如您在Form Widgets部分中看到的那样,我没有EditText图标.我知道我可以手动在xml文件中编写它,但我想知道它为什么不存在.这是我正在谈论的屏幕截图:

当不允许用户通过权威人员查看具有授权规则的页面时,我收到以下错误:

在此操作中多次调用渲染和/或重定向.请注意,您只能调用渲染或重定向,每次操作最多一次.另请注意,重定向和呈现都不会终止操作的执行,因此如果要在重定向后退出操作,则需要执行类似"redirect_to(...)并返回"的操作.

这是application_controller.rb:

class ApplicationController < ActionController::Base    
  # Includes Authorization mechanism
    include Pundit

  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  # Globally rescue Authorization Errors in controller.
  # Returning 403 Forbidden if permission is denied
  rescue_from Pundit::NotAuthorizedError, with: :permission_denied

  # Enforces access right checks for collections

尝试使用脚手架生成模型。

我在终端试过这个

mix phx.gen.model Comment comments body:text post_id:references:posts

但我在终端中得到以下信息：

** (Mix) The task "phx.gen.model" could not be found. Did you mean "phx.gen.html"?

我在终端里试过这个

mix phoenix.gen.model Comment comments body:text post_id:references:posts

但我在终端中得到以下信息：

** (Mix) The task "phoenix.gen.model" could not be found
