Patio is different because it allows the developers to choose the level of abtraction they are comfortable with. If you want to use the ORM functionality you can. If you don't you can just use the Database and Datasets as a querying API, and if you need to you can write plain SQL.

QUESTION
I have a list of services, being displayed beside the list is a picture and a description, basically when I click the list item I want the picture to change to the corresponding image/description. Right now I have the image changing onClick with hooks which is great but I'm not sure the best way to also change the descriptions. Should I make an object for each services which include the image src and then also the text? How would I go about doing that with react hooks? What would the onClick/object look like?
...ANSWER
Answered 2021-Feb-19 at 00:56Setting an object with both the image and text like you suggested would be a very reasonable suggestion. Then, your state can hold that entire object. Here's a very basic/minimal example demonstrating how that could work:
QUESTION
I'm using MariaDB and PHPMyAdmin, but my code is all neutral so happy to switch to Postgres or whatever, but this should be straight forward enough. I haven't designed anything yet, just after best approaches.
I have 3 database tables that describes a premises. Let's say a hotel.
This theoretical hotel has multiple venues - 2 restaurants and a bar. Each of those has a few different rooms/areas. In these rooms are tables that customers can sit at.
In SQL, I imagine the tables would look like this
Venues Venue ID Venue Name 1 Restaurant 1 2 Restaurant 2 3 Bar Rooms Room ID Room Name Parent Venue (foreign key) 1 Patio 1 2 Function Room 1 3 Alcove 3 4 Private Dining 2 Tables Table ID Table Name Parent Room (foreign key) 1 Table 1 1 2 Table 2 1 3 Table 3 1 4 Table 4 2 5 Table 1 3 6 Table 2 3 7 Table 3 3 8 Table 4 3 9 Table 1 4 10 Table 2 4 11 Table 3 4I hope that data is correct :p
What I want to do is define a relationship whereas it's impossible to add a Table Name if it already exists in that venue. It doesn't matter what room the table is in.
E.g if I was to add another "Table 4", it would succeed in being entered if it was entered into Room 4, as Room 4 belongs to Restaurant 2, which does not already have a "Table 4". However if it was entered into any other room, it would fail as Restaurant 1 and Bar already have a "Table 4" in one of their rooms.
Now in the server side code this is fairly easy to check as I can do multiple queries or joins or a myriad of other ways, however I was wondering how to do this in SQL/PhpMyAdmin directly. I'm having a bit of trouble finding my way around MyAdmin.
Cheers

This is a project in order to display recipes and perform many operations on these recipes such as adding, deleting and modifying, but here I want to display the recipes and to view the recipes I wrote the following code, but the recipes were never displayed in the browser. How can I solve this problem?
This file is for viewing recipes. Recipes.vue:
...ANSWER
Answered 2020-Oct-25 at 20:12First thing I can see is that it should be this.$store.state.loadedRecipes instead of this.$store.dispatch("loadedRecipes") when you load the elements from the store.
I also think you might be missing store inside the Vue instance and or the creation of the actual store.
The store should be imported like this in app.js, main.js or index.js like so:

This is a project in order to display recipes and perform many operations on them such as deleting, adding and modifying, but many times I need to have a special identification number for each item in it, but I write it manually as it is in the state. For example, when creating a recipe, I want to generate a new identification number for this recipe, and here I write it manually. The question is how can I generate it automatically when creating each recipe?

This form to create a recipe with storage by LOCAL STORAGE. In the store file, I display a set of recipes with their presentation on the interface within the "state" matrix, but when I add a recipe I want to display it in the recipes matrix "state". The problem is that the recipe is stored by localStorage, but not added to the recipe matrix "state". And in the picture, the recipe matrix is displayed How can I solve the problem?
store.js:
...ANSWER
Answered 2020-Oct-15 at 16:53In CreateRecipie.vue, You are writing data to localStorage but not to the Vuex store, and the store is not connected to the localStorage. If you write data to store then it should work properly.

QUESTION
maybe this or something like it has been answered before and that might be enough to point me in the right direction? The site loads up 24 listings at a time, then it has a see more results button, which loads the next 24, keeping the first 24 there, until you hit 96 listings, then it only keeps 96 total, however everytime I've tried to scrape it with beautiful soup I only get the first 24. Every attempt I've made with selenium has not yielded anything, I plan on looking at those failures with the documentation a little closer tomorrow and possibly adding more to this question or figuring something up, but my gut says beautiful soup is the way to go, or suck it up, copy and paste 96 at a time and deal with it with regex and or pandas (shoulder shrug emoji)
I'm trying to scrape mls listings, and have had some luck, the page loads 24 at a time, and it keeps the previous listings up for a while, using beautiful soup I can extract sales price by pulling this from the outer html

Create a new database PostgreSQL psql -c "CREATE DATABASE reademe_example" MySQL mysql -e "CREATE DATABASE readme_example"
Create a migration mkdir migration patio migration-file -n createInitialTables ./migration This will add a migration name createdInitialTables in your migration directory.
Add the following code to your migration module.exports = { //up is called when you migrate your database up up: function (db) { //create a table called state; return db .createTable("state", function () { this.primaryKey("id"); this.name(String); this.population("integer"); this.founded(Date); this.climate(String); this.description("text"); }) .chain(function () { //create another table called capital return db.createTable("capital", function () { this.primaryKey("id"); this.population("integer"); this.name(String); this.founded(Date); this.foreignKey("stateId", "state", {key: "id", onDelete: "CASCADE"}); }); }); }, //down is called when you migrate your database down down: function (db) { //drop the state and capital tables return db.dropTable("capital", "state"); } };
