I am trying to create triggers using postgresql with prisma as ORM
but it seems that it haven't supported triggers yet.
and I found this answer ,but i don't want to create my triggers logic in the server level (using middlewares).
now I am asking, can i make my triggers manually inside my database migrations as a migration level, or it may cause some problems?
for example i have the following migrations inside my application
├── prisma
│ ├── migrations
│ │ ├── 20230202011931_initial
│ │ │ └── migration.sql
│ │ ├── 20230202012555_default_to_created_at
│ │ │ └── migration.sql
│ │ ├── 20230202130457_mapping
│ │ │ └── migration.sql
│ │ └── migration_lock.toml
│ └── schema.prisma
can i choose one of these files to add my triggers inside or just create another file and add my triggers inside it?
Yes, you can declare database triggers that are a part of migrations.
You can create a migration with --create-only flag.
So invoking the command npx prisma migrate dev --create-only will create an empty migration file. You can then add the database trigger in this newly created file. Invoking npx prisma migrate dev again would then apply this new migration.
You can read more about customizing migrations here.

I am really new (just a few weeks) to C and its bulding tools. Using the CMake documetation and some other guides I created a basic CMake project. This works as expectd.
Now I wanted to use some libraries in my project (GNU readline and cJSON).
The cJSON library also uses CMake so I managed to include it in my project without too much trouble.
The GNU readline library on the other hand uses ninja and autotools (if I'm not mistaken). This is where I'm facing issues.
I am trying to build the GNU readline library to link the static files later in my project.
In the CMake documetation I saw you could use ExternalProject_Add() for the purpose of configuring and building an external project.
Just to test this I created a simple Project using CMake with ExternalProject_Add().
My test project has the following layout:
test
├── cmake-build-debug
│ ├── CMakeFiles
│ │ ├── 3.23.2
│ │ │ └── CompilerIdC
│ │ │ └── tmp
│ │ ├── CMakeTmp
│ │ ├── readline.dir
│ │ └── test.dir
│ ├── readline-prefix
│ │ ├── src
│ │ │ ├── readline-build
│ │ │ └── readline-stamp
│ │ └── tmp
│ └── Testing
│ └── Temporary
├── install_dir
└── libraries
└── readline-8.2
├── doc
├── examples
│ ├── autoconf
│ └── rlfe
├── m4
├── shlib
└── support
The library source files are located in test/libraries/readline-8.2.
I want the build files to get installed in the test/install_dir.
With the following Code I manage to build the the files, but I get errors when building it.
This is the content of my CMakeLists.txt
cmake_minimum_required(VERSION 3.23)
project(test C)
set(CMAKE_C_STANDARD 11)
set(LIB_PATH ${CMAKE_SOURCE_DIR}/libraries)
set(READLINE_LIB_SRC ${LIB_PATH}/readline-8.2)
set(CONFIGURE_ARGS --enable-shared=no --enable-install-examples=no --prefix=${CMAKE_SOURCE_DIR}/install_dir)
add_executable(test main.c)
include(ExternalProject)
ExternalProject_Add(
readline
BUILD_IN_SOURCE TRUE
BUILD_ALWAYS TRUE
SOURCE_DIR ${READLINE_LIB_SRC}
CONFIGURE_COMMAND ${READLINE_LIB_SRC}/configure ${CONFIGURE_ARGS}
BUILD_COMMAND make
INSTALL_COMMAND make install
)
I also tried adding the BUILD_BYPRODUCTS option of the ExternalProject_Add, as I read that ninja could face problems detecting targets otherwise, but without success.
The errors I get in the install step are:
mv: cannot stat '/home/devel/CLionProjects/test/install_dir/lib/libreadline.a': No such file or directory
mv: cannot stat '/home/devel/CLionProjects/test/install_dir/lib/libhistory.a': No such file or directory
But when I look at these directories the files exist.
The output of the build and the error message can be found here: https://gist.github.com/symb10sis/041f879ef5fbd02bcfd9200746101890
I couldn't include it in this question directly as it would get flagged as spam otherwise.
I spent hours reading the documetation, guides and questions here on stackoverflow but with my current knowledge of CMake I am stuck.
What causes the build to think these files don't exist? Is my use of ExternalProject_Add() appropriate for this or am I missing something?
I would really appreciate any help :)
I am trying to deploy a react personal portfolio using Vercel, but keep getting these errors. How do i fix? I also don't understand the error about img because it is in src enter image description here
code to my portfolio: https://github.com/Kdot117/Personal-portfolio
These lines in your code in Work.js are the issue.
You are importing images with absolute paths.
import BusinessCard from "/Users/kendrickizaguirre_1/kendricks-portfolio/src/BusinessCard.jpg"
import pizza from "/Users/kendrickizaguirre_1/kendricks-portfolio/src/components/pizza.jpg"
import madstat2 from "/Users/kendrickizaguirre_1/kendricks-portfolio/src/components/madstat2.jpg”
A cleaner approach (without using a library) will be to.
Make an images folder inside src.
Copy all images you are importing in js components inside this folder. or with meaningful subfolders inside the image folder.
Finally import the images in the components with the relative path.
So if I change your package structure as below.
└── Personal-portfolio
├── README.md
├── package-lock.json
├── package.json
├── public
│ ├── index.html
│ └── manifest.json
└── src
├── App.css
├── App.js
├── components
│ ├── About.js
│ ├── Contact.js
│ ├── Header.js
│ ├── Navigation.js
│ └── Work.js
├── images
│ ├── BusinessCard.jpg
│ ├── abstract.jpg
│ ├── kenny.jpg
│ ├── madstat.jpg
│ ├── madstat2.jpg
│ └── pizza.jpg
├── index.css
└── index.js
Then import in Work.js will look like this
import BusinessCard from “../images/BusinessCard.jpg"
import pizza from "../images/pizza.jpg"
import madstat2 from "../images/madstat2.jpg”
You are importing some files from an absolute path pointing to your laptop a as you can see here:
https://github.com/Kdot117/Personal-portfolio/search?q=%2Fusers%2F
Replace those with relative imports, such that
/Users/kendrickizaguirre_1/kendricks-portfolio/src/components/BusinessCard.jpg becomes src/components/BusinessCard.jpg, which will then be available also in Vercel.
BUT. Here's a better alternative. Move those images to a folder called public. And then Next.js will serve those as static files as explained here:
https://nextjs.org/docs/basic-features/static-file-serving
In this case you don't need to import anything, you would simply say <img src="/BusinessCard.jpg">
Additionally, you might want to take a look at Next Image component for optimized images out-of-the-box: https://nextjs.org/docs/basic-features/image-optimization
I am making an Android Project and I am trying to make a post request using HTTPS to a server. To make the post request I am requires to use JNI so I need to implement this in C.
My idea was to use a library that I could include into my project as i have done with the minizip library here.
I found this library here that seemed to me light engough and could server my purpose. I included in the folder c as you can also see below the files ca_cert.h, https.c and https.h along with the folder mbedtls exactly as is found on the github project.
├── app.iml
├── build.gradle
├── CMakeLists.txt
└── src
├── androidTest
│ └── java
│ └── etc
├── main
│ ├── AndroidManifest.xml
│ ├── c
│ │ ├── ca_cert.h
│ │ ├── https.c
│ │ ├── https.h
│ │ ├── mbedtls
│ │ │ ├── etc
│ │ ├── native-lib.c
│ │ ├── pathfinder.c
│ │ ├── pathfinder.h
│ │ ├── post_data.c
│ │ ├── post_data.h
│ │ ├── third
│ ├── java
│ │ └── etc
│ └── res
│ ├── etc
└── test
└── java
└── etc
As you can see in the tree structure above I have a CMakeLists.txt in the root directory and in src/main/c/ you will see the files and the folder i took from the the https library mentioned.
The contents of the CMakeLists.txt are the following
cmake_minimum_required(VERSION 3.4.1)
add_library( # Sets the name of the library.
native-lib
# Sets the library as a shared library.
SHARED
# Provides a relative path to your source file(s).
src/main/c/native-lib.c
src/main/c/ca_cert.h
src/main/c/https.h
)
include_directories(native-lib SHARED src/main/c/mbedtls/include)
#add_definitions(-DHAVE_ZLIB)
find_library( PRE_BUILD_ANDROID_LIB android)
find_library( log-lib log)
find_library(z-lib z)
target_link_libraries( native-lib
${PRE_BUILD_ANDROID_LIB}
${log-lib}
${z-lib}
)
I am missing something though for sure cause when i attempt to run a simple example like the following
JNIEXPORT jint JNICALL
Java_example_example_do_post(
JNIEnv *env,
jobject this ) {
NSV_LOGE("post_data starts\n");
char *url;
char data[1024], response[4096];
int i, ret, size;
HTTP_INFO hi1, hi2;
// Init http session. verify: check the server CA cert.
http_init(&hi1, FALSE);
http_init(&hi2, TRUE);
url = "http://httpbin.org/get?message=https_client";
ret = http_get(&hi1, url, response, sizeof(response));
return 0;
}
I get
../../../../src/main/c/native-lib.c:56: error: undefined reference to 'http_init'
../../../../src/main/c/native-lib.c:57: error: undefined reference to 'http_init'
../../../../src/main/c/native-lib.c:61: error: undefined reference to 'http_get'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Replace
src/main/c/ca_cert.h
src/main/c/https.h
with
src/main/c/https.c
in CMakeLists.txt.
I am still trying to deploy to google app engine both the local test environment and on app engine itself, and I keep getting this error:
2017/10/03 17:50:40 go-app-builder: Failed parsing input: app file DbConfig.go conflicts with same file imported from GOPATH
I have used grep to see if I explicitly import DbConfig but I, this is the result of grep:
$ grep -r 'DbConfig' .
./config.go:func GetDatabaseConfiguration() model.DbConfig {
./config.go: return model.DbConfig{connectionName, user, password, dbType, dbName}
Binary file ./share-services matches
./queries/db-config.go: dbConfig model.DbConfig
./queries/db-config.go:func Config(newDbConfig model.DbConfig) {
./queries/db-config.go: dbConfig = newDbConfig
./model/DbConfig.go:type DbConfig struct {
./model/DbConfig.go:func (d DbConfig) ConnectionString() string {
So from what I can tell I should not get an error and since other structs from my model package works just fine this is very strange to me. Firstly because Google App Engine accepts the deploy and first fails later, secondly because the dev server fails immediately, and lastly because if I run outside the app engine, I don't get this error.
Can someone give me a pointer to how to fix this please. I have search for a fix, but most state to use absolute include paths for packages which I already am.
EDIT:
I forgot to include the build command used, maybe that will help

the answer is to either use relative paths instead of absolute, which still does not totaly work Or make a 100% flat folder structure.
I have an app that uses a custom application-specific library (sap.ui.foo) which contains custom controls, views and controllers.
My deployment strategy is serving my custom library from the same server/port that is serving the index.html file.
I would also like to use SAP's CDN to load the OpenUI5 libraries (sap.m, etc).
I am using the Grunt/node tools that come with OpenUI5's GitHub repository.
When I load my application all locally (no CDN) it works perfectly, but is very slow (such a huge download payload I suppose) so I'm trying to use the CDN in hopes of improving startup performance.
My index.html looks like this: (edited after #codeworrior's answer):
<script id="sap-ui-bootstrap"
src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js"
data-sap-ui-theme="sap_bluecrystal"
data-sap-ui-libs="sap.ui.layout, sap.m, sap.ui.foo"
data-sap-ui-xx-bindingSyntax="complex"
data-sap-ui-resourceroots='{
"ns":"./",
"sap.ui.foo": "./sap/ui/foo/"
}'
>
Here is my directory structure (which to my knowledge is "standard"):
src
├── foo
│ └── src
│ └── main
│ └── webapp
│ ├── index.html # start point
│ ├── resources
│ ├── test-resources
│ └── WEB-INF
├── sap.m
├── sap.ui.commons
...other sap libs...
└── sap.ui.foo
└── src
└── sap
└── ui
└── foo
└── # my controls...
and after a grunt build:production my "target" directory looks like this:
target
├── openui5-sap.m
├── openui5-sap.ui.commons
├── openui5-sap.ui.core
├── openui5-sap.ui.demokit
├── ...other sap libs...
├── openui5-sap.ui.foo
└── resources
└── sap
└── ui
└── foo
├── Bootstrap.js
├── controllers
├── controls
├── data
├── font
├── img
├── js
├── library.js
├── library-preload.json
├── models
├── tasks
├── themes
├── util.js
├── views
└── wrappers
But, after I do a grunt serve:target and hit the url http://localhost:8989/foo/, in Chrome's dev-tools I get:
failed to preload 'sap.ui.foo.library-preload': Not Found - sap.ui.ModuleSystem
Uncaught Error: failed to load 'sap/ui/foo/library.js' from ./sap/ui/foo/library.js: 404 - Not Found
The network tab shows me that the CDN files are being served just fine, but the files that I'm trying to serve locally (such as my custom lib's library.js and library-preload.json) are 404's.
Any advice on how to get my library to load?
If your library is stored in the usual way (reflecting the full qualified names in the folder structure), then it should be sufficient to define a corresponding entry in your data-sap-ui-resourceroots attribute:
<script id="sap-ui-bootstrap"
src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js"
data-sap-ui-theme="sap_bluecrystal"
data-sap-ui-libs="sap.ui.layout, sap.m, my.uilib"
data-sap-ui-xx-bindingSyntax="complex"
data-sap-ui-resourceroots="{
ns:'./',
'my.uilib': './my/uilib/'
}">
</script>
If the structure is different, just adapt the path in the configuration. resourceRoots are configured early, so you could even specify your lib in the data-sap-ui-libs attribute.
But maybe you tried that already and it didn't work. Then the problem might have been with the spelling of the option. It's 'resourceroots', not 'resource-roots'.
