web notes - a blog

I recently upgraded a Symfony 3.3 application to Symfony 4

Part of the upgrade was loading the DataFixtures.

Symfony 4 recommends you put all your DataFixtures in a single file. I'll get around to that later. However, due to the way I organized the file system for the project, the Doctrine Fixtures Loader could not find the demo data.

To resolve the issue, I created a services_dev.yaml file with the following:

services:
    App\DataFixtures\Demo\:
        resource: '../src/DataFixtures/Demo/*'
        tags: [ doctrine.fixture.orm ]

Once I added this file to the development server, the data loaded fine.

Ref: https://symfony.com/doc/master/bundles/DoctrineFixturesBundle/index.html#multiple-files

If your iPhone is not connecting to your NetGear WNDR4000 WiFi router and the message is "Incorrect password", check the access control settings on the router.

I made a change to the router configuration and managed to enable access control which allowed only one device to log in.

Oops

My latest adventure has been to upgrade a web application from Symfony 3.3 to 4. All the pages load and I am starting to test execution.

This error came up and I scoured the code for instances of AppBundle

Then I checked the database.

One of the attributes is custom_attributes, which is a JSON column. Sample content:

[{"#type":"AppBundle\\Entity\\CustomAttribute","key":"expiration","value":"2018-02-26","valueValidExpiration":true,"valueValidChannels":true},{"#type":"AppBundle\\Entity\
\CustomAttribute","key":"channels","value":6,"valueValidExpiration":true,"valueValidChannels":true}]

I am using https://github.com/dunglas/doctrine-json-odm to provide JSON data within entities.

To change AppBundle to App, I used:

dev=# UPDATE asset SET custom_attributes= REPLACE(custom_attributes::TEXT,'AppBundle','App')::json;
UPDATE 25
dev=# UPDATE model SET custom_attributes= REPLACE(custom_attributes::TEXT,'AppBundle','App')::json;
UPDATE 9

I wasn't planning to upgrade PHP today, but in order to use Symfony 4.0, I had to.

First, I wanted to get all the PHP RPMs

sudo yum list installed php55u* | grep php | cut -f1 -d' ' | tr -d '.i686' | tr "\n" ' ' | sed "s/55/71/g" > php

Next, I removed all the PHP 5.5 RPMs:

sudo yum remove php55*

Then I edited the output file (php) and added a sudo yum install at the beginning of the file

So I could use

source php

There were a few more RPMs I needed, after roaming about the web for a bit, these were the commands that I ran

sudo yum install pear1u
sudo yum install php71u-json
sudo yum install libmemcached-devel
sudo pecl install memcached

The recklessly part of this is that I confess I did not check ... anything. My existing Symfony 3.3.10 application comes up and lets me log in. I haven't checked more than that.

Good luck!

I was using both the FixedHeader and Buttons extensions of DataTables and I needed the buttons to remain visible when the user scrolled.

The solution I chose was to move the buttons DOM into the table head.

Since the buttons are in a div and thead is part of a table, a tr is used with a td that has a colspan of the entire table.

var dtButtons = document.querySelector(".dt-buttons");
var row, cell;
row = document.createElement("tr");
cell = document.createElement("td");
cell.id = "magic-button-row";
cell.setAttribute("colspan", /*** Put the number of columns in your table here ***/);
cell.appendChild(dtButtons);
row.appendChild(cell);
document.querySelector("#display-table thead").insertBefore(row, document.querySelector("tr:first-of-type"));

There is a tiny bit of CSS, too.

#magic-button-row {
    padding: 0;
    margin: 0;
    text-align: left;
}
