            Weird interference between two DDEV projects using PostgreSQL
            Asked 2022-Mar-14 at 00:27

            I am working on two Drupal (7 and 9) projects which use PostgreSQL (based on the procedure described here). I noticed errors when they are both running at the same time: Drupal 7 will complain the variable table does not exist, while Drupal 9 will disconnect me or display some kind of WSOD. Oddly enough, they can randomly work correctly or crash again on page reload. However, it gets perfectly fine when I turn one off.

            All this makes me think of some trouble with the way I configured PostgreSQL. Could you please help me find what might be wrong in my setup?

            Here is my configuration for Drupal 9. docker-compose.postgres.yaml:



            Answered 2022-Mar-14 at 00:27

            Update for DDEV v1.19+

            1. Postgres is now available of the box with DDEV, so there is no need for an additional service/container.
            2. You no longer have to use an explicit name for the container, since the networking in DDEV is now more sophisticated.

            --------- Original Answer Below ----------

            You're using $host = "postgres";, please use the explicit name of the postgres container, ddev--postgres

            The hostname postgres is ambiguous inside the docker network when you're running more than one project that has a service named "postgres". So you're getting the behavior you see.

            A PR to the ddev-contrib recipe would be appreciated; this has been updated in lots of the ddev-contrib recipes since the problem was discovered a year or so ago, but apparently not this one.

            Fetching Data from Mysql and filling Inputs
            Asked 2021-Nov-10 at 23:44

            I've got the following mysql table (expensemonthly):

            I'm trying to fill inputs text in a form with the account_id (and account name fetch from another mysql table called "accounts"), for doing that from ajax code below I call a php file (CountFetchExpensesArrayDos.php) for creating a two dimention array:



            Answered 2021-Nov-10 at 23:44

            Your AJAX code is expecting an associative array with 3 keys: count, account_id, and name. You're not creating an associative array in the PHP code. You're just appending each account ID and name as separate array elements.

            You can create and push onto separate arrays for the account IDs and names. Then put them in the associative array when creating the JSON at the end.

            How to make database connection switchable at runtime when using SQLC
            Asked 2021-Aug-06 at 00:38

            I know this question is asked already many times, but I did not find a good answer for my case. I'm using SQLC to generate methods for querying the db. Everything is working fine when using one connection initialised at start. Now I need to set it up in a multi-tenant environment where each tenant will have a separate DB. For now I would like to start with a connection map (map[string]*sql.DB) connecting the tenant with a database connection. My question is about overriding/selecting the connection at runtime. with one connection the repository is initialised like:



            Answered 2021-Aug-06 at 00:38

            The simplest way, assuming you are using separate databases, is to maintain a map[tenantID]Repository, where tenantID is the way you differentiate between tenants (e.g. a string or uint that contains the tenant ID).

            This way you can do everything at runtime:

            • when you need to add a tenant, just instantiate the Repository for that tenant and add it to the map
            • when you need to remove a tenant, just remove its Repository from the map and close the DB connection
            • when you need to perform a query for a tenant, lookup the corresponding Repository in the map, and use it to perform the query for that tenant

            If the operations above may happen concurrently, make sure that you're using some synchronization mechanism to avoid data races when accessing the map (e.g. sync.Map, or sync.RWMutex).

            If you have a database table that stores the tenants and their DB connection URIs, you can still use this approach: when you need to perform a query check if the Repository exists in the map: if it's missing, query the tenant table and add the Repository for that tenant to the map. You can then periodically scan the map and remove any Repository that has not been used for some time.

            To make all of this easier you could also wrap the whole machinery into a MultitenantRepository interface, that is identical to the Repository interface but that accepts an additional tenantID parameter on each method:

            How to display errors for invalid login?
            Asked 2021-May-01 at 19:51

            I am trying to display the errors on the same page if anyone entered invalid login details but when invalid login details are entered a message is displayed called Array? Not sure why that's happening.

            In this code, there is a login form and if user logs in then log in, a success message appears but when details are invalid a message should appear "invalid details" which is not appearing

            I am giving simple example assuming your code is from login.php

            then you can edit as per your requirement.

            #it is just a example how to show errors. Data sanitization, preventing sql injection etc is not considered in this example.

            How to upload files to Amazon EMR?
            Asked 2021-Apr-13 at 08:00

            My code is as follows:



            Answered 2021-Apr-13 at 08:00

            Your understanding is correct.

            --files argument is uploading files to executors only.

            See this in the spark documentation

            file: - Absolute paths and file:/ URIs are served by the driver’s HTTP file server, and every executor pulls the file from the driver HTTP server.

            You can read more about this at advanced-dependency-management

            Now coming back to your second question

            How can I upload to master?

            There is a concept of bootstrap-action in EMR. From the official documentation it means the following:

            You can use a bootstrap action to install additional software or customize the configuration of cluster instances. Bootstrap actions are scripts that run on cluster after Amazon EMR launches the instance using the Amazon Linux Amazon Machine Image (AMI). Bootstrap actions run before Amazon EMR installs the applications that you specify when you create the cluster and before cluster nodes begin processing data.

            How do I use it in my case?

            While spawning the cluster you can specify your script in BootstrapActions JSON Something like the following along with other custom configurations:

            Search bar should ignore “-”, Caps and spaces (132D123 and 132 d 123 should return true) ? php
            Asked 2021-Apr-12 at 10:04

            Currently when i search the registration number 131-D-12345 I have to type the hyphens to get the results, but I wish to ignore “-”, caps and spaces (so for instance "132D123" and "132 d 123" should return true).

            How can I do that in PHP?



            Answered 2021-Apr-12 at 07:29

            Do I understand correctly that the registration numbers in the database dò contain the hyphens ?

            In that case, you should modify your query to hold wildcards (e.g. https://www.guru99.com/wildcards.html)

            As for the case, either convert the case of the PHP variable before entering it in the query ( strtoupper(), strtolower() ), or try to solve your case in your table definition.

            If the database entries do not hold the hyphens, you can filter them out the variable using a replace or preg_replace() to remove them.


            if I assume your database holds very uniform inputs, like this :

            why i'm getting the following error "Data truncated for column 'model' at row 1"
            Asked 2021-Apr-07 at 22:38

            So I want to get the user data from the form and then store it in the database but i'm getting the error "Data truncated for column 'model' at row 1" when I try to add the details.

            I am using the radio button so the user can pick 1 make and 1 model related to that make and then want those details to be added to the database under appropriate headings as in MySQL table table below

            html form code:



            Answered 2021-Apr-07 at 22:38

            The problem is that PHP doesn't know that it should only use the value of Model from the dropdown below the selected radio button. It uses the value of the last one. If the user leaves that one unselected, the value "" doesn't correspond to any of the ENUM values, so you get an error.

            You can give them distinct names, and then select the appropriate one based on the radio button.

            Does Go's sqlc supports join?
            Asked 2021-Feb-16 at 08:55

            I was reading the documentation for SQLC from https://docs.sqlc.dev/en/latest/howto/query_count.html. I wanted to use this in my project. However, I'm not seeing any documentation related to joining operations on the tables. Is it really possible in SQLC. If yes where I could find the documentation or reference?

            A commit like "cdf7025: Add MySQL json test" (or "456fcb1 Add MySQL test for SELECT * JOIN") suggests joins are supported.

            But it is true, as mentioned in issue 643, that queries with JOINs are for now not documented yet.

            pyspark dataframe maximum time at every folder level
            Asked 2021-Feb-10 at 19:28

            I would like to recursively find the maximum date-time value of each subfolder and finally find the top parent's maximum timestamp. spark SQL is slower when I run. So I would like to implement this logic using UDF or data frame methods in pyspark.



            Answered 2021-Feb-10 at 19:25
            1. add a column base_folder that contains only the folder part without the file, that will be used for joinning
            2. group by base_folder and calculate max timestamp
            3. join with original dataframe using base_folder and get max timestamp for rows where it's null
