QUESTION
I want to use Python to read and write YAML frontmatter in markdown files. I have come across the ruamel.yaml package but am having trouble understanding how to use it for this purpose.
If I have a markdown file:
...ANSWER
Answered 2021-Jun-14 at 11:35When you have multiple YAML documents in one file these are separated with a line consisting of
three dashes, or starting with three dashes followed by a space.
Most YAML parsers, including ruamel.yaml either expect a single document file (when using YAML().load())
or a multi-document file (when using YAML().load_all()).
The method .load() returns the single data structure, and complains if there seems to be more than one
document (i.e. when it encounters the second --- in your file). The
.load_all() method can handle one or more YAML documents, but always returns
an iterator.
Your input happens to be a valid multi-document YAML file but the markdown part often makes this not be the case. It easily could
always have been valid YAML by just changing the second --- into --- | thereby making the
markdown part a (multi-line) literal scalar string. I have no idea why the
designers of such YAML frontmatter formats didn't specify that, it might have to
do that some parsers (like PyYAML) fail to parse such non-indented literal scalar
strings at the root level correctly, although examples of those are in the YAML
specification.
In your example the markdown part is so simple that it is valid YAML without
having to specify the | for literal scalar string. So you could use
.load_all() on this input. But just adding e.g. a line
starting with a dash to the markdown section, will result in an invalid YAML
document, so you if you use .load_all(), you have to make sure you
do not iterate so far as to parse the second document:

Answered 2021-Jun-06 at 11:05Queried data is inside props.data, destructured as { data }. Page queries, the one you are showing in your SEO component are only available in the top-level components (pages).
The idea when dealing with this kind of component is to move the query for each page you want and drill down the data to the SEO component through props. For example:

QUESTION
I'm trying to get the array of element refs that are not in v-for. I'm using @nuxtjs/composition-api on Nuxt 2.
(Truth: I want to make an array of input elements, so that I can perform validations on them before submit)
This sounds too easy on vue 2 as $refs becomes an array when one or more compnents have the same ref name on html. However, this doesn't sound simple with composition api and trying to perform simple task with that got me stuck from long.
So to handle this scenario, I've created 1 composable function. (Soruce: https://v3.vuejs.org/guide/migration/array-refs.html#frontmatter-title)
...ANSWER
Answered 2021-May-26 at 15:13Nuxt 2 is based on Vue 2, which only accepts strings for the ref attribute. The docs you linked actually refer to new behavior in Vue 3 for ref, where functions are also accepted.
Template refs in Nuxt 2 work the same way as they do in Vue 2 with Composition API: When a ref is inside a v-for, the ref becomes an array:
QUESTION
I am learning to create a gatsby blog website with a YouTube tutorial. I have followed the exact steps as shown in the tutorials. There were errors that were related to graphql query format. which were solved.
I have searched for the error. But all the answers were related to react app. There was no answers related to gatsby. So I was unable to figure out the right way to solve it.
The page loads at local server port 8000. The error comes while clicking the Read more button to see the single post. The error seems to be of React.
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of singlePost.
